While tracking down another random issue, I noticed the following error message in my maillog:
Jun 14 19:49:21 server3 dovecot: imap-login: imap-login: error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memorySome quick research led me to this page.
Essentially, if you're getting this message, you need to open up your dovecot configuration file and find this section:
# Set max. process size in megabytes. If you don't use # login_process_per_connection you might need to grow this. #login_process_size = 32Uncomment the last line, and change it to:
login_process_size = 64That should resolve the problem.
Joe, do you think there's any way to make this default in the configuration?
