This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig9974404EA4D02F034F4DBD75 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable The problem happens regardless of whether I compile the jdk with or without ipv6 support, however I do have an IPv6 address as well as an ipv4 one. I use subclipse-1.6.2, this is the only thing that I think will use TCP/IP (does subclipse run the command line client or do the connection itself?). The only other things that will use TCP/IP are the unit tests, but eclipse will often crash before I have run any. The error is intermittent it can happen 10 times in 5 minutes or once a day. It seems to be more stable if I turn off "Build automatically" (which will presumably reduces the amount of concurrency), it also seems to crash most often when opening or closing projects. However, it is so intermittent that my observations could well be luck related. I have compiled my jdk with debug symbols and looking at the core dump with gdb gives the following stack trace for the thread that bombs: (gdb) ba #0 0x00000008007acd2c in thr_kill () from /lib/libc.so.7 #1 0x000000080083c2bb in abort () from /lib/libc.so.7 #2 0x0000000800fe2d69 in os::abort () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #3 0x00000008011175cf in VMError::report_and_die () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #4 0x0000000800fe618b in JVM_handle_bsd_signal () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #5 <signal handler called> #6 0x0000000800d0c724 in PhaseChaitin::gather_lrg_masks () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #7 0x0000000800d0e392 in PhaseChaitin::Register_Allocate () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #8 0x0000000800d5e303 in Compile::Code_Gen () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #9 0x0000000800d5f948 in Compile::Compile () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #10 0x0000000800cfac98 in C2Compiler::compile_method () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #11 0x0000000800d6377d in CompileBroker::invoke_compiler_on_method () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #12 0x0000000800d64505 in CompileBroker::compiler_thread_loop () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #13 0x00000008010d6bad in JavaThread::thread_main_inner () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #14 0x0000000800fe53f6 in java_start () from /usr/local/diablo-jdk1.6.0/jre/lib/amd64/server/libjvm.so #15 0x000000080064b4d1 in pthread_getprio () from /lib/libthr.so.3 #16 0x0000000000000000 in ?? () Cannot access memory at address 0x7ffffeef2000 Looks like the signal happens in PhaseChaitin::gather_lrg_masks whatever that is. Also note that tomcat6 is stable, but I do not load tomcat very much at all (only ever has one occasional HTTP client, so no request concurrency)= =2E At the moment my jdk is compiled with ipv6 support, I am going to try compiling it again with this option off. I will use a portupgrade -fR eclipse so that all upstream dependencies are also recompiled.
