https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236220 Julien Cigar <julien@perdition.city> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |julien@perdition.city --- Comment #14 from Julien Cigar <julien@perdition.city> --- I'm also experimenting something similar on 12.0-RELEASE + ZFS, also running PostgreSQL 11 (in jail, with nullfs mounts). I've seen this on two machines. The first one is a small HPE Proliant Microserver Gen 8 with 16GB RAM. It started when I upgraded from 10.3 to 12.0, so I don't know if 11.x is affected too. As OP, sometimes I can remote SSH, sometimes not, and a simple ls almost always hangs. A shutdown -r now hangs too after syncing buffers. For some unknow reason the problem didn't occured again (3 months now) since I forced ARC_MAX to 8GB (vfs.zfs.arc_max=8589934592). The second one is an HPE Proliant DL160Gen9 with 64GB of RAM (freshly installed 12.0-RELEASE). Symptoms are the same as above, with ARC_MAX set to 24GB (vfs.zfs.arc_max=25769803776). (I'll try to procstat -kk -a next time) -- You are receiving this mail because: You are the assignee for the bug.
