CORE3262: Crash occurred in function JVM_RaiseSignal

We have Sun App Server 7 and using JAVA 1.4.2 version based application developed using struts framwork. When we deploy EAR file after doing the build and execute the application it works fine. Problem starts when trying to debug application by starting application instance in debug mode in app server and catch in Eclipse SDK 3.2.1

Server crashes giving following error in the server.log [default log level set to FIINE]

[01/Mar/2007:16:52:21] FATAL ( 4989): CORE3260: Server crash detected (signal SIGSEGV)

[01/Mar/2007:16:52:21] INFO ( 4989): CORE3262: Crash occurred in function JVM_RaiseSignal from module /usr/j2se/jre/l

ib/sparc/server/libjvm.so

[01/Mar/2007:16:52:21] SEVERE ( 4988): CORE3107: Child process closed admin channel

Please help or give us a pointer to find a solution
