https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241980 --- Comment #1 from Eugene Grosbein <eugen@freebsd.org> --- The system routinely creates snapshots for ZVOLs and removes old snapshots,= so gstat -adI3s -f 'da[2-6].*' shows that system constandly floods SSDs with A= TA TRIM requests. I decreased kern.cam.da.[2-6].delete_max from default 17179607040 to 262144 after 1.5 days since update to 11.3-STABLE hoping to decrease latency of read/write operations but it panices again in several hours after that. --=20 You are receiving this mail because: You are the assignee for the bug.=
