Thank you very much! Probably you are right. Our users use shared IMAP
folders and sometimes they keep ten thousands of messages in one folder.
I have increased dirhash_maxmem to 64MB and see what happens.
If find / -sx is running and is consuming all CPU, what is the value of
# sysctl -a | grep dirhash
shopzeus# sysctl -a | grep dirhash
All right. It is close to it. Which one should I increase? I put this
Make sure vfs.ufs.dirhash_mem: is not close to vfs.ufs.dirhash_maxmem:
Would it be scufficient?
We don't know, and can't tell you. You'll have to monitor
vfs.ufs.dirhash_mem occasionally to see if you start to reach
I have a tendency to use vfs.ufs.dirhash_maxmem=16777216, which is
I'm not fully confident this is what's causing your problem, but it's
definitely a recommendation by Johan.
Unfortunately, I cannot play with the hardware because it is in a server
park, and it must be up 99.99% on workdays.
I hope dirhash will solve the problem. I'm setting this to [SOLVED] and
come back if it happens again. (Maybe on monday?)
By the way, there is nothing in /etc/periodic that would execute "find /
-sx". Can somebody explain what is this for, and why it was started by
root? Is it being used instead for enumerating files in a directory,
when dir hash is full?
