Hi, Thanks for finding this out. Ccing to the syslog-ng list. postfix is chrooted, and thus cannot reopen log connections from the chrooted jail. if one runs postfix it is advisably to fetch logs from /var/spool/postfix/dev/log It's not syslog-ng specific though. Nate could you add this to the FAQ? On Wed, Oct 09, 2002 at 03:05:07PM +0200, Dr. Peter Bieringer wrote:

2) after restarting syslog-ng, postfix/nqmgr do no longer log
That's very strange, I don't find a solution until now. Do you have hints?
this is a libc issue IMHO, libc doesn't immediately reopen log connections if sending a message fails. as you restart syslog-ng the connections to the previous instance of syslog-ng are lost.
Looks like through a magic mechanism, logging works on startup also by the chrooted-postfix process. To reestablish the log on syslog-ng restart, the log socket has to be connected again:

Perhaps an entry for a FAQ. Also the one with the too few log connect limits.
