I think it=E2= =80=99s really important to find out a solution for this issue together. I can see two behaviors related, but for me the root cause is the same: 1- mpd5 process stuck with umtxn flag 2- system crash I=E2=80=99ve tested recently on FreeBSD 10.3 and FreeBSD-11-RC3. I=E2=80=99= ve tried all suggested tunings with no success. My environment is: - About 430 clients connected (but i can add more) - Using ZFS - igb NICs. - Generic kernel Two days ago i updated my system to FreeBSD 11-RELEASE-p1 and after this my system seems stable for almost 3 days. No crashes anymore. I need more days to feel confident if something has changed. But anyway, my crashes before happened every day. If it crashs again i=E2=80=99ll apply Donald recommendation and let you guy= s know. Let=E2=80=99s keep in touch, to try to at last fix it. Thanks.
