 Posted: Wed May 31, 2006 9:07 pm Post subject: saslauthd uses more and more memory |
 |
|
since updating cyrus-sasl to 2.1.21-r2, saslauthd uses more and more memory including swap (400MB of 512MB last) - 1GB RAM is installed. I never hat to restart the daemon before, but now i have to do this every day. I don't know where to search for the cause, but i think there's somebody here who can help.
The server has to do with about 2000 eMails per day...
make.conf:

My cyrus-sasl-2.1.22-r1 is eating memory (including swap), too. Is there a solution out there yet? Thanks in advance.

I'm seeing the samething on a mail server with 4GB of RAM and 5GB swap. After about 5 - 7 days total memory exhaustion incluiding swap and the server crashes. A quick check with ps shows saslauthd is eating all the memory. Re-starting the process fixes the problem but i have todo that every 2 - 3 days.

saslauthd has some issues on my server as well, spiking to 100% cpu, never going away. My solution (a fairly safe one) is to restart saslauthd via the init script every hour.
