Hi Steve, Build was started and I run Jconsole and at the time when Heap space problem occurred following is the jconsole output :

Junit is always forked while I run my junit tests. I would run jconsole and let you know the results. Thanks Ravi. -----Original Message----- From: Steve Loughran [mailto:[EMAIL PROTECTED] Sent: Monday, December 10, 2007 9:15 PM To: Ant Users List Subject: Re: Frequent java.lang.OutOfMemoryError: Java heap space error Ravi Roy wrote: > Hello all, > > I am running my product build with cruisecontrol using ant 1.7.0.

It is more frequent now. 1. run jconsole against the running java processes to identify the memory hogs 2. it may be that its cruise control running ant in process that is consuming the memory, and that different env variables need setting 3. fork junit, javac and other process (separate JVM that gets cleaned up) 4. Are you using Ivy or other third-party ant tasks? I'd be pretty surprised that you are running out at 1.5GB; that will result in a footprint over the 2GB mark -steve PS: (top proceses on my machine right now: vm physical shared 2319m 1.1g 15m S 94 18.9 248:35.14 java 2051m 475m 19m S 30 7.9 71:55.36 java 769m 569m 553m S 22 9.5 40:26.57 vmware-v IDEA at the top, then netbeans, finally XP in a VMware image. I'm playing with Netbeans as IDEA is getting too sluggish. -- Steve Loughran http://www.1060.org/blogxter/publish/5 Author: Ant in Action http://antbook.org/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
