[JBoss-user] [Performance Tuning] - Re: Eden space increasing by 10Mb every minute and GC'ing ba
Hi I haven't checked this on JBoss but this pattern is consistent with the heap usage patterns on other containers and application servers. It is due to the application server threads running in the background and the objects allocated/GC'd for that purpose. This is not something to be concerned about, unless the amount of heap in use increases over time (ie, look at the heap usage for each valley before/after GC activity and if this increases, then this could point to an application server/application leak). Also, 0-10Mb is not a particularly large delta so I would not be too concerned here. If it was going from 0-100+Mb then I would perform additional analysis. Since this is JBoss, you may wish to look at the AppServer slimming/tuning wiki to see if there are any services you can turn off/remove. This will have an impact on performance, and probably also on the heap usage. Hope this helps.

[JBoss-user] [Performance Tuning] - Re: OutofMemory Problem
Hi Jagadeesh The size of the war file will have very little impact on you receiving the OutOfMemoryException. Typically, this can be caused by either your application creating Objects on the Heap where a reference is retained to the Object (memory leak) or through resource contention. What size of Heap do you have set? How much physical memory is available? What is the size of the various generations and the permanent space? You also want to address questions like: what Objects are being allocated in my application? which ones are surviving garbage collections? To answer the latter, you should use some kind of memory profiling tool to find these loitering objects and remove the references. You will also want to examine the various JVM settings you have set and have available to you. Hope this helps Mark View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3925633#3925633 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3925633 --- This SF.net email is sponsored by: Splunk Inc.
