Just noted similar after upgrading web servers to 13.0-RELEASE, and same st= ill in place for 13.1-RLEASE. After upgrade servers worked no more than several days until memory exhaust= ed, then reboot required. Switching 'sendfile on' to 'sendfile off' in nginx config helped and servers now works stable for months, however monitoring (poor munin, I can provide graphs if required) still show strange vm behaviour which I didn't observe = in 11.1-RELEASE. No ZFS used, only UFS. Probably this will give clue and help in investigation. Thanks. --=20 You are receiving this mail because: You are the assignee for the bug.=
