https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229829 --- Comment #2 from Martin Birgmeier <d8zNeCFG@aon.at> --- Scenarios, continued: - server up, scrub of pool is continuing - gstat is running - 2 VirtualBox VMs are running - another VirtualBox VM is accessing a zvol via iSCSI (ctl) Result: - The machine freezes: not immediately, but process after process gets stuck Scenario continued: - After 30 minutes watching this, perform hard reset - Start single user - "fsck -p" -> cleans UFS root fs - issue "zpool export pool" in order to start multiuser without the pool be= ing imported Result: - The scrubbing starts again immediately, no command prompt Scenario continued: - Issue "ifconfig <interface> inet <hostname>" into console buffer - Issue "ifconfig <interface> inet6 <hostname>" into console buffer - On another machine, wait until ping succeeds Result: - First ping after ca. 20 minutes (see previous scenarios) - Console shows that 20G gmirror for swap has been rebuilt - pool is exported I am running with https://reviews.freebsd.org/D7538 applied because otherwi= se the system was slowly filling all swap space and swapping continuously, even with no activity. Something is very wrong in FreeBSD 11.2 with ZFS, swapping, and memory management. I did not have these problems with 11.1. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
