Hi,
Nagios 2.0b5 on Solaris 10. I've been running this
setup for some time and just recently started seeing "Internal
Server Error" on page refreshes from Firefox, with Apache
reporting "Premature end of script headers". The only changes
recently are that I increased the host and service checks
significantly (up to 250 and 5200 respectively) and I moved
status.dat from a UFS file system to /tmp (tmpfs) per the
performance page tip #2 on using RAM-based filesystem for it.
I searched the mailing list archives and turned on debug
level logging in Apache but it doesn't report any more.
If I run status.cgi from command line, it dumps core for
a seg fault as shown below. I tried the status.cgi from 2.3 with
the same results. If I move status.dat back to disk, the CGI
errors stop, but I still get a seg fault running from command
line. There are no core files created when the error occurs from
Apache. Any idea why this may be occuring? Here's some command
line output.
bash-3.00$ ./status.cgi
Cache-Control: no-store
Pragma: no-cache
