Make sure all databases (built via postalias, ...) are in
good working order. Rebuild them all from the plaintext
source files.
Use netstat/lsof to find processes listening on or connected to
various sockets in /var/spool/postfix/private, which sockets have
the most processes?
Relevant things to check:
- Kernel resource limits, perhaps you need to run fewer processes.
- Which program appears the largest number of times in "ps" output.
- Is there a lot of mail in the deferred queue?
- Are you generating postmaster notices that may make the problem
worse?
How many local(8) processes are running? What files does the oldest
of them have open? How long have they been running? Is there any
logging from postfix/local? ... Is there any logging by local
other than successful deliveries (if any).
Is local(8) able to read the passwd file, or are that file's permissions
broken? Run (id -nu) as "postfix" does it work?
