I had this very strange problem this morning, maybe concerning to the  
above too!

Several of our master processes went away without any good reason!   
This was the first time.

mail19/lmtp[31757]: unable to tell master 2: Broken pipe

For the moments where it happened it was all at ~7:30 AM.  Just at the  
same time we run cyr_expire!

cyrus.conf:

   delprune      cmd="/usr/cyrus-2.4.6/bin/cyr_expire -C  
/etc/cyrus-ugent/conf/mail15/imapd.conf -D 31 -E 8 -X 31" at=0730

I was not aware of the imapd.conf delayed_expung parameter!  So it is  
still the default.  Previously -D and -X was set to 7!  I changed that  
exactly one week ago to 31.

However, cyr_expire runs ok:

pruning back 8 days

purged 2108 out of 134761 entries
