Hi, I just want to report a similar issue here with 11.2-RELEASE-p8.
The affected machine has 64 GB ram and does daily backups from several machines in the night, at daytime there a parallel runs of clamav on a specific dataset. One symtom is basic I/O-performance: After upgrading from 11.1 to 11.2 backup times have increased, and are even still increasing. After one week of operation, backup times have doubled - without having changed anything else. Then there is this wired memory and way too lazy reclaim of memory for user processes: The clamav scans start at 10:30 and get swapped out immediatly. Although vfs.zfs.arc_max=48G, wired is at 62 GB before the scans and it takes about 10 minutes for the scan processes to actually run on system ram, not swap. There is obviously something broken, as there are several threads with similar observations. with kind regards, Robert Schulze _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
