Hi Current,
It seems like there is constant flow (leak) of memory from ARC to Inact in
FreeBSD 11.0-CURRENT #0 r273165.
Normally, our system (FreeBSD 11.0-CURRENT #5 r260625) keeps ARC size very
close to vfs.zfs.arc_max:
Mem: 16G Active, 324M Inact, 105G Wired, 1612M Cache, 3308M Buf, 1094M F

Hi all,
On our production system on r255173 we have problem with abnormal high system
load caused (not sure) with L2ARC placed on a few SSD, 490 GB total size.
After a fresh boot everything seems to be fine, Load Average less then 5.00.
But after some time (nearly day-two) Load Average jump to 1
Hi all
On CURRENT r255173 we have some interesting values from vmstat -z : REQ = FAIL
[server]# vmstat -z
ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP
... skipped
NCLNODE: 528, 0, 0, 0, 0, 0, 0
space_seg_cache:
Please, any idea, thougth, help!
Maybe what information can be useful for diggin - anything...
System what I'm talkin about has a huge problem: performance degradation in
short time period (day-two). Don't know can we somehow relate this vmstat fails
with degradation.
