Hi!
I'm running 1.1rc4 on a system and this happens occasionally:
--8<-- mail.info; dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=NN.NN.NN.NN rip=NNN.NN.NNN.NN lport=143 mail.info; dovecot: auth-worker(default): pam(XXXXXXXXXXXX,NNN.NN.NNN.NN): lookup service=imap kern.alert; kernel: grsec: From NN.NN.NN.NN: denied resource overstep by requesting 134242304 for RLIMIT_AS against limit 134217728 for /us authpriv.err; dovecot-auth: PAM unable to dlopen(/lib/security/pam_unix.so) authpriv.err; dovecot-auth: PAM [error: /lib/security/pam_unix.so: failed to map segment from shared object: Cannot allocate memory] authpriv.err; dovecot-auth: PAM adding faulty module: /lib/security/pam_unix.so mail.err; dovecot: auth-worker(default): pam(XXXXXXXXXXXX,NNN.NN.NNN.NN): pam_authenticate() failed: Authentication failure mail.info; dovecot: auth(default): new auth connection: pid=6262 mail.info; dovecot: auth(default): client out: FAIL 1 user=XXXXXXXXXXXX --8<--
When I restart dovecot, it runs fine for a while, then it starts happening again. I'm pretty unsure about the cause, can someone give me a hint?
