Re: Out of Memory exception (hotspot compilation)
Hello, Just wanted to update on this issue. Atlassian support confirms that this is a known issue with Java 6.0_18 and up. So, the best solution for now is to use 6.0_17 Here - http://jira.atlassian.com/browse/CONF-19049http://jira.atlassian.com/browse/CONF-19049?focusedCommentId=197013#action_197013 Regards, Leon Kolchinsky On Thu, Jun 3, 2010 at 16:14, Leon Rosenberg rosenberg.l...@gmail.comwrote: On Thu, Jun 3, 2010 at 1:54 AM, Leon Kolchinsky lkolc...@gmail.com wrote: Yep :) You're right Charles.

Out of Memory exception (hotspot compilation)
Hi, I noticed in recent emails that Leon Kolchinsky was running Tomcat and Java requested 2GB of memory unexpectedly then died due to an out of memory exception. Bizarrely, the same thing happened to me today with very similar symptoms. Specifically, the JVM requested 8GB of memory while hotspot was trying to compile the exact same Velocity/Foreach method as Leon's example. I'm running 64 bit JDK 1.6.0_18-b07 / Tomcat 6.0.24 / APR 1.1.19. I wanted to highlight this, (someone was talking about posting a bug report). Since it's the exact same method, I'm guessing the Velocity method triggers a bug in the hotspot compilation. Note that we've been running this configuration for 5 months and I haven't seen this previously, so it's probably rare. Excerpt from hs_err -- java.lang.OutOfMemoryError: requested 8589934608 bytes for Chunk::new. Out of swap space?

Re: Out of Memory exception (hotspot compilation)
The JDK has been the same since early February. I don't think there's been any other system upgrades. (it's possible there was a upgrade to the OS I'm not aware of, but definitely not the JDK).
