FWIW, just did an upgrade on some systems. All preices machines, all were running -39
Upgraded to -48, this bug appeared. Rolled back the clients only to -39, bug disappeared. Site is a semi heavy web service with 1 NFS server, and 2 NFS clients running nginx/php. Issue was seen almost immediately upon nginx/php starting up, lots of threads got stuck, load went up due to high I/O wait. fstab: 10.1.2.3:/www /data/www nfs defaults 0 0 exports: /data/shared 10.1.2.0/24(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash) /data/shared/www 10.1.2.0/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/932687 Title: nfs4_reclaim_locks: unhandled error crashes applications and creates high load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/932687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
