railo java heap space error Cherry, Illinois

How to slow down sessions? Give me an example What is the solution? Do I also need returntype="void" (I don't need a return)?My other question is: I've used async CFCs since they came out to run my long-running background jobs because it seemed like I put everything in a number of cfsilent tags, and it ran for one night, but now it is crashing again.I'm not sure what to do next.

Mar 16, 2010 9:21 AM (in response to TLC-IT) One of the characteristics of ColdFusion, particularly when you are using CFML tags vs. s, is that it is very easy for Instruct your JVM to dump the contents of its heap memory into a file. Do you think you can call it just once and things go crazy this way? But then when I plugged that same code into the async CFC, I saw it resume accumulating memory as it ran--the per-iteration cleanup didn't seem to be happening.So it seems like

You can change the amount of memory allocated for use by your JVM using the -Xms and -Xmx command line parameters. If works perfectly in the fifteen minute version that works with a subset of the data, but it frequently runs coldfusion out of java heap in the full record set run. We know that most of our competitors just can't deliver. Related articles ColdFusion Performance Enhancement Recommendations Railo/Lucee and IIS Settings How do I change my site URL?

Next, you need to figure out where in your source code the potentially hazardous large amount of objects is being allocated. Save the file and restart the services. Give me an example What is the solution? I will admit this is not a very scientific approach, but later on down the line when I have time I will hook up JConsole and really see whats going on.

If you liked this article or found it helpful and want to say thanks you can always buy me something from my wish list :-) Reader Comments Post a Comment Comment It really is very good at turning up sub-optimal code, which when fixed bring good performance gains. The async part appears to be somewhat immaterial now--I ran it as a straight call to a cfc/method and had the same memory accumulation issue. What I set out to do was to minimize the time spent in garbage collection since I have some heavy use of memory sometimes when deploying new code and running scheduled

It also does the necessary data processing for you - on the fly, as soon as the JVM encounters an java.lang.OutOfMemoryError. Do you have any confirmation that you're ONLY doing things the number of times you expect? On the other hand, every heap dump “freezes” the JVM entirely, so don’t take too many of them or your end users start swearing. What is causing it?

Unable to create new native thread What is causing it? It takes care of gathering the necessary data behind the scenes - this includes the relevant data about heap usage (only the object layout graph, no actual data), and also some This will take several minutes during which the intranet will not be available.(Note, you must restart the web server, not just the website). This forms a vicious cycle where the CPU is 100% busy with GC and no actual work can be done.

They all give the command that has to be executed, what I don't understand is where do I write this command. As expected, the heap dump was not interpreted (i.e. The default value is 640K. (The -server flag increases the default size to 2M.) -Xmx size in bytes Sets the maximum size to which the Java heap can grow. Open this file for editing and look for this line: Download Code Snippet JAVA_OPTS="-Xms128m -Xmx256m -XX:MaxPermSize=64m "; There are three settings in megabytes here that we can modify: Xms: The minimum

This happens each time through the loop. I don't have time to verify every options is faster or slower, but the main goal was to reduce garbage collection pauses, and I have. When your JVM-to-troubleshoot uses for example 8GB of heap, you need a machine with more than 8GB to be able to analyze heap contents.

The variables are in cffunction with var keyword with output="no" on the cffunction with coldfusion debugging checkboxes unchecked in the admin so in theory the fifteenth step/cffunction in the process should The async gateway is only called once (confirmed by the counts in the admin), and the loop is iterating as it should and executing the code in the loop just once Email But running it as a cfm cleans up the memory on every iteration of the loop.

Re: "Java heap space" error and coldfusion crashes ifsteve Apr 2, 2013 9:20 AM (in response to carl type3) I know this is an old threat, but its the most detailed If the error happens right away, then you can increase memory still further, or investigate find out why so much memory is needed for one file. Dropping $7K instead of $1K for the same product is a hard sell at my company.I don't have FusionReactor either. It does warn that if you make it too high, it will eventually switch back to regular pages or cause memory issues with other software.

Metaspace What is causing it? If the intranet returns an error page, restore the backed up applicationhost.config file and restart the webserver again. This allowed all the variables used in the previous refresh to go to garbage collection and eventually get cleared out while new requests where processing other reports.
