https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235582 --- Comment #16 from Peter Eriksson <peter.x.eriksson@liu.se> --- I agree that the debug printout stuff is not the problem here. We are going to try out your second patch on our production servers this we= ek. (Just had one of the servers (without your patch) crash and reboot again twice). Thankfully we found a way to speed up the mounting of 20k zfs filesystems massively so a reboot now takes about 5 minutes instead of 40+ minutes... (A coworker wrote a script that does the ZFS mounts in parallell instead of sequentially - there are room for even more speed improvements though :-) Anyway - a question about a potential workaround: Would limiting the number of NFSD thread with "-n 1" "mask" this problem?=20 Our servers have 32 cpu "cores" so nfsd tries to start up 256 kernel threads which I'm guessing will improve the chance of the bug to be triggered. --=20 You are receiving this mail because: You are the assignee for the bug.=
