Public bug reported: Starting two instances of a program called pcgamess causes bad things to happen on a dapper SMP kernel.
I receive this error message: [43342099.730000] double fault, gdt at dffdd000 [255 bytes] Another message is logged also logged about a soft error on the CPU and is usually followed by a kernel dump. A tarball of the binaries that do this can be retrieved here: http://w3.physics.uiuc.edu/~ajw/gamess.tgz Run the crashme.sh script. With the sleep between starting processes, it might not crash the machine, but the double fault should happen. If the sleep is removed the system immediately crashes in all of my testing. I've tested this on an SMP Redhat Enterprise 4 machine and it doesn't crash the system, but I do get errors like this: p4_error: OOPS: semop lock failed So maybe there is some problems with IPC? ** Affects: linux-source-2.6.15 (Ubuntu) Importance: Undecided Status: New -- double fault and kernel crash running pcgamess https://bugs.launchpad.net/bugs/130694 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
