4

My application started crashing after we migrate it to 64bit. The crash is occuring every 2-3 days on our production linux server. We are using jdk1.6.0_15-x86_64. The crash is happening at the same place when my application uses the Xalan transformer to convert XSLT to HTML.

I have confirmed that this is not happening on our 32bit server and not happening when the application doesn't perform the XSLT to HTML convertion. So it happens only when convertion happens on 64bit server.

Any help will be highly appreciated.

  • do you use the same memory settings for both the 32bit and 64bit jvms? be aware that the same code running in a 64bit jvm will use a fair bit more memory due to the change in reference(pointer) sizes. – jtahlborn Sep 06 '12 at 20:39

    Update 15 is very old and lots of bugs have been fixed since then, I would try Java 6 update 35 or Java 7 update 7. http://www.oracle.com/technetwork/java/javase/releasenotes-136954.html – Peter Lawrey Sep 06 '12 at 20:58
  • In 32bit version our application used to configure using -Xms800m -Xmx800m and now in 64bit verion it has been increased to -Xms1400m -Xmx1400m – user1617151 Sep 06 '12 at 21:33

It seems your permgen is being corrupted which could be due to the fact that your code trying to load libraries. I suspect the libraries being loaded by following code may not be compatible with 64 bit JVM.

Before filing a bug with JVM, I would check in program following lines of code, which seems culprit.

  • I would suggest add XX:+UseCodeCacheFlushin also – kosa Sep 06 '12 at 20:30
  • Is there a way to find whether the libraries are compatible with 64bit JVM? – user1617151 Sep 06 '12 at 20:36
  • May be check the version of libraries and go to their website and see release notes. – kosa Sep 06 '12 at 20:37
  • @jtahlborn: though I agree with your statement, this is not issue with heap, this is issue with Permgen. – kosa Sep 06 '12 at 20:40
  • @jtahlborn/Nambari - checked the permgen size when the application doesn't crash, it always shows 99% but the total and used is lower than 40M. So I believe the 40M is only allocated total and it is not the maximum permgen. Thoughts? – – user1617151 Sep 06 '12 at 21:37

I'd suggest increasing the perm gen space (-XX:MaxPermSize) and enabling GC on it (-XX:+CMSPermGenSweepingEnabled) -- 40M isn't much! If you are loading a lot of libraries, I'd also suggest enabling class unloading (-XX:+CMSClassUnloadingEnabled). Note that if you really do have a memory leak, this will only give you more breathing room between crashes, you still need to fix the underlying cause.
