  Threads That Won’t Die: Fixing ColdFusion ExecutorService Leaks After Reload Your ColdFusion application creates a Java ExecutorService to run background tasks. It works well, processing work on a pool of threads. Then you reload the application, and the old threads keep running. Reload again, and more threads pile up, until the server runs out of resources. Read More

  Debugging in the Dark: Closing ColdFusion Observability Gaps A production incident strikes your ColdFusion application. Users report slowdowns, and pressure mounts to fix it fast. Then you open the logs and find little to go on. The messages are vague, scattered, and impossible to connect to a single request. Read More

  You roll out a new ColdFusion version with a canary deployment. A small slice of traffic hits the new version while most users stay on the stable one. Then errors appear. The stable version starts throwing database errors, or the canary cannot find columns it expects. Read More

  Out of Connections: Fixing ColdFusion LDAP Exhaustion During Login Spikes Your ColdFusion application authenticates users against LDAP without trouble most of the day. Then a login spike arrives, perhaps at shift change or after an outage. Suddenly, logins fail or hang. The directory is healthy, yet ColdFusion cannot connect to it. Read More

  Your ColdFusion application subscribes to a Redis channel for real-time events. It works in testing, and messages flow through. Then in production, messages go missing. Some arrive, some do not, and the pattern seems random. Read More

  You migrate a ColdFusion container to a new node in your cluster. The pod reschedules, and the volume reattaches. Then files come back damaged. Uploads are truncated, logs are garbled, and the application throws filesystem errors. Read More

  Your ColdFusion application runs fine in Kubernetes for a while. Then pods start restarting for no obvious reason. The restart count climbs, and the logs show a healthy application. Yet Kubernetes keeps killing and restarting the containers. Read More

  Gone After the Upgrade: Fixing ColdFusion Truststore Mismatch After a Java Update You upgrade the Java version under ColdFusion for security and support. The upgrade completes, and ColdFusion starts normally. Then every outbound HTTPS call begins to fail. Integrations that worked for years suddenly throw certificate errors. Read More

  Stale Data From the Cache: Fixing ColdFusion ORM Second-Level Cache Inconsistencies Your ColdFusion ORM application caches entities for speed. The second-level cache slashes database load impressively. Then a user updates a record, and the trouble begins. Some parts of the application still show the old data. Read More

  You built a ColdFusion cluster for reliability and scale. Multiple servers share the load behind a balancer. Then users report a maddening problem. They log in, click a link, and suddenly they are logged out again. Read More

The Pauses GC Logs Never Show You: Diagnosing ColdFusion Safepoint Latency   Your ColdFusion application shows unpredictable latency spikes. Most requests return in milliseconds. Then a handful take hundreds of milliseconds for no visible reason. Meanwhile, the garbage collection logs look perfectly healthy. Read More

  The Slow Leak: Why Continuous Deployments Exhaust ColdFusion Metaspace Your ColdFusion application runs perfectly after a restart. Then you deploy an update, and another, and another. Days later, the server crashes with a memory error. Yet the heap looks healthy the entire time. Read More

  ColdFusion modal popups power contact forms, login dialogs, data entry panels, and confirmation screens. Therefore, reliable form submission from inside a modal is a core enterprise requirement. Yet developers consistently hit a wall. The button clicks, nothing posts, and the user stares at a frozen popup. Read More

  ColdFusion generates PDFs for invoices, reports, statements, and contracts. Therefore, reliable PDF delivery sits at the core of many enterprise apps. Yet developers often watch a cfdocument output fail in the browser. The page shows a blank frame, a download prompt, or corrupted bytes. Read More

  Introduction The integration works perfectly in staging. The mobile app calls the payment API through ColdFusion. Tokens authenticate. Transactions process. Then deployment to production fails with a cryptic message: “I/O Exception: sun.security.validator.ValidatorException: PKIX path building failed: java.security.cert.CertPathBuilderException: Could not build a validated path.” The API is up. Browsers connect to it without errors. Curl from the production server works fine. But ColdFusion refuses to talk to it. The error message points at Java security internals that most CFML developers have never read. Read More

The integration runs flawlessly during the demo. Tokens authenticate cleanly. API calls succeed. Then an hour later, every call starts returning 401 Unauthorized. The integration sees the failure, refreshes the token, retries the call, and succeeds. The user experience is fine — but every hour, a brief window of failures occurs while the code reacts to expiration. Then twenty-four hours later, the failures stop being temporary. The refresh attempts also return 401. The refresh token expired. Users are silently logged out. The integration breaks completely until someone manually triggers re-authentication. Read More

  Introduction The mobile app posts JSON to the ColdFusion REST endpoint. The endpoint returns “500 Internal Server Error” with no body, no useful header information, and no error message that helps diagnose the problem. The frontend developer asks the backend developer for help. The backend developer checks the ColdFusion error log — nothing recent. The exception log — empty. The Application.cfc onError handler — never fired. The endpoint works in Postman with the right request body. It fails with a 500 when the mobile app sends what looks like an identical request. The cause is invisible from every diagnostic angle except one — and that one is buried in a stack trace nobody thought to check. Read More

  Introduction The user types José in the form. The browser sends “José” correctly. ColdFusion processes the request. The database stores “Jos?”. The user types Москва. The database stores “??????”. The user types 中文. The database stores “??”. Or worse — the data appears correct in SQL Server Management Studio but corrupts the moment ColdFusion reads it back. Every test in isolation works. The full pipeline silently destroys non-ASCII characters somewhere between keyboard and disk. Read More

  Introduction The code reads two database tables. It updates an inventory record. It inserts an order line. It updates the customer’s loyalty balance. Halfway through, the loyalty update fails — the column does not exist on the customer table after a schema change nobody documented. ColdFusion throws an error. You expect the transaction to roll back. You expect the inventory and order records to revert. You expect the database to look exactly as it did before the operation started. You expect atomicity. What you get is an inventory record that decremented, an order line that exists with a phantom customer reference, and an error log entry that says nothing about why the rollback failed. Read More

  Applying the latest Adobe ColdFusion security update (APSB) does not update the underlying Oracle JDK that ColdFusion runs on. Adobe ships ColdFusion 2021 with Java 11, 2023 with Java 17, and 2025 with Java 21 — but the bundled JRE folder is frozen at whatever Java version shipped with the installer. Oracle releases JDK security patches quarterly, and recent Critical Patch Updates have closed unauthenticated, network-exploitable flaws in Java SE itself. If your CF team patches CF but never touches the JDK, your server keeps every Java-level CVE Oracle has fixed since your install — even after every APSB is current. The fix is a separate, manual JDK update process documented by Adobe. Read More
