------- Comment From [email protected] 2015-10-31 17:59 EDT------- It looks like a non-zero return from do_execve() in ____call_usermodehelper() is the primary trigger here.
if (!retval) return 0; do_exit(0); A successful callout bypasses the do_exit() process accounting. While trying to debug the nfsidmap utility, I typoed a path and the resulting callout returned 127. My test system locked up just like the customer's. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509120 Title: Process accounting deadlock with idmapd callout when writing to NFSv4 mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509120/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
