How did you set this up?

It looks like send_nsca is segfaulting, but this could have any number of causes, could you attach the core dump from /var/spool/abrt/ccpp-2014-06-17-04:17:02-8526 ?

Code: Select all

Saved core dump of pid 8526 (/usr/local/nagios/libexec/send_nsca) to /var/spool/abrt/ccpp-2014-06-17-04:17:02-8526 (380928 bytes)

It is not showing anything with that file name

tmproot@usa0300lv846>ls -lrt /var/spool/abrt/ccpp-2014-06-17-04:17:02-8526
ls: cannot access /var/spool/abrt/ccpp-2014-06-17-04:17:02-8526: No such file or directory

It looks like it could possibly be contained in "last-ccpp", though I'd think it would be the file name that you saw in the log. Is that all you have in (/var/spool/abrt/) ?

[ravish78]

Yes only those 3 files are visible in that path.

tmproot@usa0300lv846>ls -lrt

[tmcdonald]

Go ahead and attach the last-ccpp

[ravish78]

tmproot@usa0300lv846>cat last-ccpp
/usr/local/nagios/libexec/send_nsca
tmproot@usa0300lv846>


Can we open an incident as it is effecting production environment
