If you have recently updated your Red Hat Enterprise Linux Server release 5.1 (Tikanga) / CentOS 5.1, dovecot imap server might give out the following error:
Nov 5 13:21:13 p5ora1 dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory
Nov 5 13:21:13 p5ora1 dovecot: pop3-login: pop3-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory
This error is not related to shared libraries. You need to set maximum process size in megabytes. If you don’t use login_process_per_connection you might need to grow this. Just open /etc/dovecot.conf file
# vi /etc/dovecot.conf
Find line read as follows:
login_process_size
Uncomment and set it to 64:
login_process_size = 64
Save and close the file. Restart dovecot imap server:
# /etc/init.d/dovecot restart
The Dovecot package on x86_64 (64 bit system) kernels requires the parameter “login_process_size = 64” to be added to /etc/dovecot.conf after an upgrade to RHEL / CentOS 5.1.

Using ispconfig in a virtuozzo linux redhat/centos environment 64 bit. Glad I stumbled across this posting saved me alot of time. Thank you!
Thanks. Anyone know why this was needed though? What specifically was the change that required more memory for dovecot?
Awesome! Thanks so much for posting this, definitely made my day otherwise I would have been banging against SELinux trying to figure what voodoo needed.
wow – thanks! that saved me heaps of time!!!
Thanks! This was just a great troubleshoot!
Thanks, this was a very easy and fast fix. You’re the first hit on Google!
