[Dovecot] Initial status notification not received

[Nicolas KOWALSKI]

Hello,

We have SLES-11 SP2 Xen VMs running dovecot as IMAP proxies. At VMs 
startup, dovecot almost always shows these errors:

Nov 16 14:29:19 server dovecot: master: Dovecot v2.1.10 starting up (core dumps disabled)
Nov 16 14:29:55 server dovecot: master: Error: service(anvil): Initial status notification not received in 30 seconds, killing the process
Nov 16 14:29:55 server dovecot: master: Error: service(log): Initial status notification not received in 30 seconds, killing the process
Nov 16 14:29:55 server dovecot: master: Error: service(ssl-params): Initial status notification not received in 30 seconds, killing the process
Nov 16 14:29:55 server dovecot: master: Error: service(log): child 3591 killed with signal 9

As the last line tells, dovecot stops logging information. We have to 
restart the dovecot processes to get back normal behaviour. I also tried 
to set idle_kill values to services definitions, without success.

Is there a way to prevent these errors?


Here is the dovecot -n output:
