2010-09-25 08:51:17 Michal Heriban description im programing a simple app which uses many threads and mysql connection the jvm crashes in a few minutes after the threads are continuously created. i suspect it has something to do with the way linux manages threads (NPTL) i use a static threadlocal instance,which initializes a mysql connection i've encountered this on different hardware : intel e6850 , 6gb ram hp probook 4520s core i3 350m, 4gb ram i've tried to find a fix via google for many hours but found nothing useful or remotely helpful the same app runs flawlessly on windows 7 x64 jdk from sun,i've also tried the jdk from sun on linux,but the same problem arises is there any way to choose something different than NPTL ? # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f565248e065, pid=2356, tid=140007445153552 # # JRE version: 6.0_18-b18 # Java VM: OpenJDK 64-Bit Server VM (16.0-b13 mixed mode linux-amd64 ) # Derivative: IcedTea6 1.8.1 # Distribution: Ubuntu 10.04 LTS, package 6b18-1.8.1-0ubuntu1 # Problematic frame: # V [libjvm.so+0x5a5065] # # An error report file with more information is saved as: # /home/michal/praca/stefan/webrozhranie/webrozhranie/hs_err_pid2356.log # # If you would like to submit a bug report, please include # instructions how to reproduce the bug and visit: # https://bugs.launchpad.net/ubuntu/+source/openjdk-6/ # im programing a simple app which uses many threads and mysql connection the jvm crashes in a few minutes after the threads are continuously created. the problem only arises when debugging from eclipse i suspect it has something to do with the way linux manages threads (NPTL) i use a static threadlocal instance,which initializes a mysql connection i've encountered this on different hardware : intel e6850 , 6gb ram hp probook 4520s core i3 350m, 4gb ram i've tried to find a fix via google for many hours but found nothing useful or remotely helpful the same app runs flawlessly on windows 7 x64 jdk from sun,i've also tried the jdk from sun on linux,but the same problem arises is there any way to choose something different than NPTL ? # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f565248e065, pid=2356, tid=140007445153552 # # JRE version: 6.0_18-b18 # Java VM: OpenJDK 64-Bit Server VM (16.0-b13 mixed mode linux-amd64 ) # Derivative: IcedTea6 1.8.1 # Distribution: Ubuntu 10.04 LTS, package 6b18-1.8.1-0ubuntu1 # Problematic frame: # V [libjvm.so+0x5a5065] # # An error report file with more information is saved as: # /home/michal/praca/stefan/webrozhranie/webrozhranie/hs_err_pid2356.log # # If you would like to submit a bug report, please include # instructions how to reproduce the bug and visit: # https://bugs.launchpad.net/ubuntu/+source/openjdk-6/ #
