macos-2.0.0-rc6 Memory Leak?

Postby dereed999 » Fri Apr 30, 2021 11:16 am

I have a raidz3 pool (90TB ish) and seem to have a memory leak. When accessing files on either the native ZFS file system or on zvols formatted w/ HFS+ the system will eventually reboot after exhausting all memory. A vm_stat in a while loop shows the wired down pages increasing more or less monotonically and then eventually swapins/outs starting to happen and then an eventual panic. If I run the system but with the pool exported I never run into any issues. So it seems to be related to the zfs subsystem/extension.

I can reproduce it by doing a read loop of copying files from the filesystem.
For instance, on a ZVOL formatted with HFS+ filled with media files, the following
Code: Select all
find . -type f -exec cat {} > /dev/null \;

will trigger the eventual crash. I did all I could to quiesce all other activity and looking at lsof saw no other activity on the volume.

Thoughts on how I can help track down where the memory leak could be coming from?

If it helps, my pool doesn't have all the latest features enabled. In particular, a zpool upgrade informs me the following aren't enabled:
userobj_accounting
project_quota
redaction_bookmarks
redacted_datasets
bookmark_written
log_spacemap
livelist
device_rebuild
zstd_compress
draid


Thanks!

# sysctl kstat | grep inuse

Would show all the memory areas and how much memory they are using. Usually they will go up initially, but eventually find some balance and hover around some amount. If you find one "ever-increasing" then we should take a look at it.

Additionally, kstat.vmem.vmem.spl_default_arena.mem_inuse is the grand total memory we have taken from XNU.

The last check before panic gave the following. The device only has 64GB of RAM...

Re: macos-2.0.0-rc6 Memory Leak?

Postby lundman » Sat May 01, 2021 4:25 pm

This is certainly interesting:
Code: Select all
kstat.vmem.vmem.bucket_16384.mem_inuse: 109793280.   = 00.1G
kstat.vmem.vmem.bucket_32768.mem_inuse: 1991430144. = 01.8G
kstat.vmem.vmem.bucket_65536.mem_inuse: 35545858048 = 33.0G
kstat.vmem.vmem.bucket_131072.mem_inuse: 81625088
kstat.vmem.vmem.bucket_262144.mem_inuse: 1409024


So it certainly looks like a leak in 64KB blocks. You can probably confirm that by running;

sudo log stream --source --predicate 'sender == "zfs"' --style compact

in a window, then run;

zpool export -a
kextunload -b org.openzfsonosx.zfs

to unload the kext, it will complain about leaked memory it detects.

Can we also confirm you dont have anything in /etc/zfs/zsysctl.conf ?

I don't have that file.

I followed the directions, but had to modify the kextunload command to be: kextunload /Library/Extensions/zfs.kext as the "-n" option didn't work for some reason.

Ok that should have been "-b" and not "-n" (I updated my post to be correct now)

Yes, that is a leak. Let me try to see if get any here, but if I can not, I could build you a leak-tracer version and it will show exactly where it leaks. But it will only
do one range at a time.

I think I'm seeing this too. I've had a number of watchdog panics after extended periods of activity on a 6-core i7 32Gb Mac Mini with two large-ish pools.

Just unloading the kext today shows (after just a bit more than 24hr up time):

Re: macos-2.0.0-rc6 Memory Leak?

Did you say your macOS version? BigSur? I'll build a memleak test size == 24 first, run for a bit, then do the unload and it should say where it is leaked from.
