We do have some scheduled tasks on the server, but they're largely once a day things, with the exception of one that runs every 30 minutes, and one every 6 hours. The times don't remotely match up, and don't remotely conform to those intervals. Additionally, scheduled tasks show up in the logs with a ThreadID of [DefaultQuartzScheduler_Worker-x] where x is a number, like so: Dec 15, 2016 16:37:00 PM Information [DefaultQuartzScheduler_Worker-4] - Task default. [NAME OF TASK] triggered. Dec 15, 2016 16:37:00 PM Information [DefaultQuartzScheduler_Worker-4] - Starting HTTP request {URL='[URL OF TASK]', method='get'} Dec 15, 2016 16:37:00 PM Information [DefaultQuartzScheduler_Worker-4] - HTTP request completed {Status Code=200 ,Time taken=47 ms} All the normal requests are handled via ThreadID [ajp-nio-8016-exec-x] where x is a number. Dec 15, 2016 16:37:53 PM Error [ajp-nio-8016-exec-6] - File not found: [NONEXISTENT FILE] The specific sequence of files included or processed is: [FILEPATH]'' Dec 15, 2016 16:37:55 PM Information [ajp-nio-8016-exec-4] - Starting HTTP request {URL='[REMOTE URL]', method='get'} Dec 15, 2016 16:37:56 PM Information [ajp-nio-8016-exec-4] - HTTP request completed {Status Code=200 ,Time taken=516 ms} Whereas when the actual error occurs, you can see it's executed by the [scheduler-x] ThreadIDs (and then I'm promptly sent an email about it): Dec 15, 2016 16:46:15 PM Error [scheduler-2] - '' The specific sequence of files included or processed is: '''' Dec 15, 2016 16:46:24 PM Information [scheduler-0] - Mail: 'New Error' From:'site_error@[SITE].com' To:'[MY EMAIL]' was successfully sent using [MAIL SERVER] The only thing besides sending error emails and metrics (before I disabled metrics logging so I could actually read the logs easily) that [scheduler-x] does is: Dec 15, 2016 15:00:05 PM Information [scheduler-0] - Run Client Storage Purge Well, besides my lovely inexplicable Dec 15, 2016 14:56:02 PM Error [scheduler-0] - '' The specific sequence of files included or processed is: '''' Thoughts?

The problem started with a normal, full of stuff onsessionend. We slowly pared it down until it was completely empty and the problem still persisted/persists. Originally I believed it was happening at the end of every session, but we eventually figured out that the error doesn't happen on normal session endings. Only when these weird scheduler things happen.

Sessions are enabled at top of Application.cfc, per usual. <cfcomponent output="false"> <cfset this.name = "[applicationname]" /> <cfset this.applicationTimeout = createTimeSpan(5,0,0,0) /> <cfset this.loginStorage = "session" /> <cfset this.scriptProtect = "all" /> <cfset this.serverSideFormValidation = "no" /> <cfset this.sessioncookie.httponly = "yes" /> <cfset this.sessionManagement = "yes" /> <cfset this.sessionTimeout = createTimeSpan(0,0,30,0) /> <cfset this.setclientcookies = "no"> etc. etc. JVM arguments: -server -XX:MaxMetaspaceSize=192m -XX:+UseParallelGC -Xbatch -Dcoldfusion.home={application.home} -Duser.language=en -Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true -Dcoldfusion.jsafe.defaultalgo=FIPS186Random -Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.JavaUtilLog -Djava.util.logging.config.file={application.home}/lib/logging.properties CF is the only thing using JVM on the machine.

Some background: we recently upgraded from CF 10 to CF 2016, and moved to a new server (Windows Server 2012 R2, IIS 8). All updates are installed for all of the above (cf version 2016.0.03.300466 and jvm version: 25.72-b15). Here's the issue: In my Application.cfc I've got a completely empty onSessionEnd. <cffunction name="onSessionEnd" returnType="void"> <cfargument name="SessionScope" required="true" /> <cfargument name="ApplicationScope" required="false" /> </cffunction> I've got onError is currently set up to send me an email. I am periodically getting this: arguments - struct EVENTNAME onSessionEnd EXCEPTION arguments - struct Cause arguments - struct Message [empty string] StackTrace java.lang.NullPointerException at coldfusion.runtime.NeoJspWriter.writeOutput(NeoJspWriter.java:228) at coldfusion.runtime.NeoJspWriter.flush(NeoJspWriter.java:362) at coldfusion.cfc.CFCProxy.flush(CFCProxy.java:357) at coldfusion.cfc.CFCProxy.doInvoke(CFCProxy.java:332) at coldfusion.cfc.CFCProxy.invoke(CFCProxy.java:302) at coldfusion.runtime.AppEventInvoker.onSessionEnd(AppEventInvoker.java:462) at coldfusion.runtime.SessionTracker.invokeOnSessinEnd(SessionTracker.java:291) at coldfusion.runtime.SessionTracker.cleanUp(SessionTracker.java:274) at coldfusion.runtime.SessionTracker.access$000(SessionTracker.java:43) at coldfusion.runtime.SessionTracker$SessionCleanUpAgent.run(SessionTracker.java:483) at coldfusion.scheduling.ThreadPool.run(ThreadPool.java:260) at coldfusion.scheduling.WorkerThread.run(WorkerThread.java:71) Suppressed arguments - array [empty] TagContext arguments - array [empty] Type java.lang.NullPointerException Detail An exception occurred while invoking an event handler method from Application.cfc. The method name is: onSessionEnd. Message Event handler exception. I'm basically at a loss as to how it's generating a nullPointerException (which, to my understanding, can sometimes be basically a variable undefined error when encountered in onSessionEnd or onApplicationEnd which aren't handled well by onError, but as there's literally nothing in it, that's not relevant). So I dug into the logs.
