Code will append a line o the file every second. Again, I can't seem to terminate to stop the filewrite. Just doesn't work. I've been doing CFML 20+ years but haven't worked with threads much and so I'm courious if anyone else here has suggestion

component {

function terminate(){ for(thread in application.memoryUsage.threadNames){ try { thread action="terminate" name=thread; writeOutput('terminated #thread#<br>'); } catch (any e) { writeOutput(e.message & '<br>'); } } } function logMemory(threadName){ if(!isDefined('application.memoryUsage.threadNames')) { application.memoryUsage.threadNames = []; } arrayPrepend(application.memoryUsage.threadNames,arguments.threadName); if(arrayLen(application.memoryUsage.threadNames) > 3){ application.memoryUsage.threadNames = arraySlice(application.memoryUsage.threadNames, 1, 3); }; thread action="run" name=application.memoryUsage.threadNames[1] { application.memoryUsage.mem = memUsage('MEMLOGINTERVAL'); local.fileName = ExpandPath('logs\memLog_#DateFormat(now(),'yyyy-mm-dd')#.csv'); if(!fileExists(local.fileName)) FileWrite(local.fileName, 'total,max,used,free,used_pct,timestamp' & Chr(13) & Chr(10)); local.fileObj = FileOpen(local.fileName, "append"); FileWriteLine(local.fileObj,application.memoryUsage.mem.total & ',' & application.memoryUsage.mem.max & ',' & application.memoryUsage.mem.used & ',' & application.memoryUsage.mem.free & ',' & application.memoryUsage.mem.used_pct & ',' & application.memoryUsage.mem.timestamp); FileClose(local.fileObj); } sleep(1000); logMemory(threadName=CreateUUID()); thread action="join" name=ArrayToList(application.memoryUsage.threadNames); } // Returns total/free memory returned from java.lang.Runtime function memUsage(systemvar){ application.memoryUsage.javaObj = { system: createObject("java", "java.lang.System"), runtime: createObject("java", "java.lang.Runtime").getRuntime() }; return { total: application.memoryUsage.javaObj.runtime.totalMemory(), // Returns the total amount of memory in the Java virtual machine. max: application.memoryUsage.javaObj.runtime.maxMemory(), // Returns the maximum amount of memory that the Java virtual machine will attempt to use. used: application.memoryUsage.javaObj.runtime.totalMemory() - application.memoryUsage.javaObj.runtime.freeMemory(), free: application.memoryUsage.javaObj.runtime.freeMemory(), // Returns the amount of free memory in the Java Virtual Machine. used_pct: round(application.memoryUsage.javaObj.runtime.maxMemory() / ( application.memoryUsage.javaObj.runtime.totalMemory() - application.memoryUsage.javaObj.runtime.freeMemory() )), // % of max memory used, timestamp: DateFormat(now(),"yyyy-MM-dd HHmmss") }; }

@bdw429s??

And native code (like writing a file) can't be interrupted by design (In Java)

So the question is now long the write is taking

If the write takes a long time, then you just have to wait (unless you want to write the file via Java which is quite messy)

If the writes are fast, but happen often, then usually putting some code that is easily interruptible like

sleep( 100 )

will help. A sleep will throw an interuptedException when the thread gets interrupted.

But as Samuel said, there are probably several existing tools out there which will do this much better.
