Hi nick
Try to do the following :
ulimit -c unlimited
that will make it coredump instead.
then, next time you start it, it should make a core file ser.core or
something like that.
When that´s done, do :
gdb �-c ser.core(orwhatthecorefileiscalled)ser
this will open gdb, so you can run a backtrace.
type :
bt
and you will get the backtrace. Past it here, and maybe somebody can see
what´s wrong :-)
Best regards,
Atle

OK, got the core dumps working did a gdb -c on the first coredump file

To explain my situation, I've got a dual
opteron 246 system with 1gig of ram and 2 80gig disks in raid1 (software raid), I'm
running CentOS 4.3 x86_64 with kernel 2.6.9-34.ELsmp I'm running ser 0.9.6-6 (the
-6 may just be an artifact from the fedora core rpm.. I dunno) (compiled from
ser-0.9.6_src.tar.gz)
Since no one seems to makes rpms for redhat or centOS (the same thing obviously) I went
and made my own. I grabbed a fedora core 6 src rpm, and modified the specfile to my own
liking (basically I took out
the stuff related to postgres), the compile went fine, as far as I can tell, no errors
were big enough to stop the compilation at least, and the rpms installed just fine. All
the modules are in the right
place, and my ser.cfg seems to be correct (I don't get any more errors during
startup), however, I do get a segfault :(
here's the attached output from /log/messages

Obviously ser isn't running, does anyone have any idea where I can start looking to
find out what dies/died/went wrong with the compile?
Thanks,
Nick
