Postfix's proxmap is segfaulting or at least that's what I think the signal
11 means. Some background info first: This is a fedora mail server (core 6)
that I've upgraded to postfix 2.5.4. I used the rpm spec file from the last
release of postfix on fc6 to build a rpm to upgrade with and also to make
sure I keep the file system layout as close as possible to fedora's postfix
packages. Any how, I had to make some heavy modifications to the spec file
to get everything to mesh but it seemed to work out okay but ultimately I
think that I have caused this problem by doing so. Tonight I noticed that
proxymap is segfaulting. I'm not sure what proxymap does exactly but it
hasn't affected normal operation of the server I'm testing on to the best I
can tell. All the same I'd like to address the problem.
According to the debug readme, I changed master.cf:
proxymap unix - - n - - proxymap -D
I added this line to main.cf which isn't showing up in postconf -n's output
for some reason even after postfix reload:
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
(strace -p $process_id 2>&1 | tee /var/log/postfix_debug.log |
logger -p mail.info) & sleep 5
As you've probably noticed, I changed the debug command slightly from what
was in the debug readme to have the output written to syslog and a custom
log file. So instead of the segfault now I'm seeing this and getting nothing
else in mail.info or my custom log file about proxymap and I'm wondering
I've done something wrong:

l.error) & sleep 5
