This crash seems to be related to a JVM bug. It sounds quite strange that a method requires more than 100MB heap for Jit Compilation. You can find several similar failure reports in the hotspot bug database.
In this case it could be useful to monitor the following parameters through jvmstat: 1) sun.ci.lastFailedMethod You should be able to identify which JIT compilation event leads to the failure of the JVM. (You can also write a little JVMTI agent implementing the compiledMethodLoad callback function). 2) sun.ci.lastFailedType Once the faulty method has been identified it can be excluded from jit compilation creating a .hotspot_compiler file (including the name of the methods to exclude preceeded by the 'exclude' keyword) and passing this file to the JVM through the -XX:CompileCommandFile option. 3) sun.ci.nmethodSize If several failures are observed, and they occur upon JIT-compilation of different methods there may exist a problem with the native code cache. This parameter allows you to monitor the usage of this area (by default on LinuxX86 the JVM reserves 48M to this aim) -----Messaggio originale----- Da: Stefano Bagnara [mailto:[EMAIL PROTECTED] Inviato: mercoledì 28 marzo 2007 0.40 A: James Users List Oggetto: Re: Exception - Out of Memory - Out of swap space?

Given your memory numbers and your error I guess you have a memory leak in the JVM code or in a JNI component. My steps: 1) Check your Mailets (and expecially JNI code you may have) 2) Collect hints: > jmap -permstat <pid> > jstat -class <pid> > jstat -options (maybe run all of them and paste... don't know if there is anything useful, but it should be easy to do). 3) Upgrade jvm to 1.5.0_11 4) Downgrade jvm to 1.4.2_13 Stefano --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- No virus found in this incoming message.
