[Dovecot] 1.0.3 - PAM child process timed out, killing it = logs are full.

Tere.

I'm running 1.0.3 in RedHat for some time, few days ago also upgraded 
1.0.0 to 1.0.3 on Debian Sarge, 64 machine.

But now message log runs like crazy (about 10 GB since yesterday 
evening) with such errors:

Aug 30 05:57:09 stan dovecot: auth(default):
pam(user1,172.18.1.25): PAM child process 1266 timed out, killing it
Aug 30 05:57:09 stan dovecot: auth(default): pam(user2,172.18.18.44):

Aug 30 05:57:09 stan dovecot: auth(default):
pam(user6,172.18.18.33): PAM child process 29383 timed out, killing it

Whats wrong? Compiled from source, with the same options, as always?
