Hello,
I use Solaris Live Upgrade to install solaris patches in an alternate boot environment. Unfortunately the dovecot sockets /opt/local/var/run/dovecot/dict-server and /opt/local/var/run/dovecot/login/default are created as normal files in the ABE. After switching to the ABE dovecot will not start because of the existence of these two files. After removing these files dovecot starts normally. I think that dovecot should create the sockets even if there exist files with the same names. Here is the protocol of this:
Dovecot uses two sockets in the running system:
# ls -al /opt/local/var/run/dovecot/login/default /opt/local/var/run/dovecot/dict-server
srwxrwxrwx 1 root root 0 Aug 4 10:07 /opt/local/var/run/dovecot/dict-server
srw-rw---- 1 root dovecot 0 Aug 4 10:07 /opt/local/var/run/dovecot/login/default
In the Alternate Boot Environment created with Solaris Live Upgrade there are normal files instead of the sockets:
# ls -al /a/opt/local/var/run/dovecot/login/default /a/opt/local/var/run/dovecot/login/default
-rw-rw---- 1 root dovecot 0 Jul 7 17:01 /a/opt/local/var/run/dovecot/login/default
-rw-rw---- 1 root dovecot 0 Jul 7 17:01 /a/opt/local/var/run/dovecot/login/default
During booting this ABE dovecot will not start, unless both files are removed:
Aug 6 06:55:30 hostname dovecot: Fatal: Socket already exists: /opt/local/var/run/dovecot/dict-server
# ls -al /opt/local/var/run/dovecot/dict-server
-rwxrwxrwx 1 root root 0 Aug 4 10:09 /opt/local/var/run/dovecot/dict-server
# rm /opt/local/var/run/dovecot/dict-server
# /etc/init.d/dovecot start
Last died with error (see error log for more information): Socket already exists: /opt/local/var/run/dovecot/dict-server
Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.info] Dovecot v1.2.12 starting up
Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.error] net_listen_unix(/opt/local/var/run/dovecot/login/default) failed: Address already in use
Aug 6 06:57:50 hostname dovecot: [ID 583609 local0.crit] Fatal: Couldn't create auth process listener
# ls -al /opt/local/var/run/dovecot/dict-server
srwxrwxrwx 1 root other 0 Aug 6 06:57 /opt/local/var/run/dovecot/dict-server
# ls -al /opt/local/var/run/dovecot/login/default
-rw-rw---- 1 root dovecot 0 Aug 4 10:09 /opt/local/var/run/dovecot/login/default
# rm /opt/local/var/run/dovecot/login/default
# /etc/init.d/dovecot start
# ls -al /opt/local/var/run/dovecot/login/default
srw-rw---- 1 root dovecot 0 Aug 6 07:00 /opt/local/var/run/dovecot/login/default
Both sockets are created by dovecot if they don't exist.

Jürgen Obermann
