https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237429 --- Comment #13 from Rodney W. Grimes <rgrimes@FreeBSD.org> --- (In reply to doctor from comment #11) I am concerned that you have loaded zfs, you have no pool what so ever present on this machine? So my assumption is neither did 11.2, so please can you remove zfs, just so we know in no possible way is that having an effect. I am pretty sure that zfs grabs a chunk of memory at boot time even if you just load it and never do a zpool import, but it should not be a very big chunk. If in fact you do have a pool, even if your not using it, zfs is going to import it and suck up a bunch of your memory. I am not so interested in a large chunk of top data, however a single shot of "ps alwwx" would be of interest if you could get one during the slow down phase. At this stage I am pretty convinced this is additional memory pressure and or system tuning changes that came with 12.0. It does have a slightly larger memory foot print, and there are a fairly extensive amount of vm system changes between 11.2 and 12.0. -- You are receiving this mail because: You are the assignee for the bug.
