Hello,

 

I've noticed that courier-authlib slowly uses up memory over time on my
Gentoo linux server. Using 2.6.21-gentoo-r4 kernel,  compiler GCC 4.1.2,
glibc 2.5-r4. Using the authvchkpw library, authdaemond usage looks like
this after about a week:

 

top - 00:42:49 up 22 days, 20:31,  2 users,  load average: 2.08, 2.52, 2.54

Tasks: 271 total,   2 running, 269 sleeping,   0 stopped,   0 zombie

Mem:   2074712k total,  1966420k used,   108292k free,   134520k buffers

Swap:  1951800k total,  1113692k used,   838108k free,   547588k cached

Once I restart the service, usage looks much better:

>From /etc/courier/authlib/authdaemonrc:

authmodulelist="authvchkpw "

daemons="5"

LOGGEROPTS=""

There is another post on the courier-users mailing list about this, user is
also using a Gentoo environment and he was told to post on the vchkpw
mailing list. Link included for reference:

Any input would be greatly appreciated.
