Re: Cyrus squatter using only a single core

Hi,

Quoting "Fabio S. Schmidt" <fabio@xxxxxxxxxxxxxx>:

Hi !

I'm running Cyrus 2.4.14 on Debian 6 64 Bits and I've noticed that when
squatter is running it only uses a single core. Has this behavior been
improved on newer versions?

Here is my entry:

squatter_1    cmd="/usr/bin/nice +n 19 /usr/lib/cyrus/bin/squatter -s -i -r
user" period=180


i think you are running the squatter to often.

period=180 will run it every 3h. If there is more then one sqatter running,
it second will catch up and the proceses will have to wait for the mailbox
lock.

We run our squatter, expire and backup once each night, when there is less
IO traffic.

you can use at= instead of period=. See cyrus.conf manpage for details

I do run it with "nice +19" but It causes a high load on the core it's
running and triggers an alert on my monitoring solution. I know that this
alert could be deactivated, but maybe I'm doing something wrong with
squatter.
