https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237429 --- 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 pres= ent 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 cha= nges between 11.2 and 12.0. --=20 You are receiving this mail because: You are the assignee for the bug.
