How do I get this information? Please include a link to hs_err_pid1832.log. Also, anything you can do to cut down what is needed to reproduce would be helpful. I don't think many people likely have such a set up. In that case there may well be some back and forth to gather more information from the crashes unless the crash file is clearer. > Also: should I file a bug report? Yes please. > I will re-run using the regular GC to see if this is perhaps G1 related. It seems unlikely, but that would rule it out for sure. > [kjkoster@dill ~]$ uname -a > FreeBSD dill.beta-monitor.com 9.0-STABLE FreeBSD 9.0-STABLE #0: Tue Jun 19 11:46:32 UTC 2012 root@dill.beta-monitor.com:/usr/obj/usr/src/sys/DILL amd64 > [kjkoster@dill ~]$ /usr/local/openjdk7/bin/java -version > openjdk version "1.7.0_04" > OpenJDK Runtime Environment (build 1.7.0_04-b22) > OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode) > > # > # A fatal error has been detected by the Java Runtime Environment: > # > # SIGSEGV (0xb) at pc=0x00000008a6218243, pid=1832, tid=34455804928 > # > # JRE version: 7.0-b22 > # Java VM: OpenJDK 64-Bit Server VM (23.0-b21 mixed mode bsd-amd64 compressed oops) > # Problematic frame: > # C [libnet.so+0x9243] Java_java_net_SocketInputStream_socketRead0+0xb3 > # > # Failed to write core dump.
