[users@httpd] CGI defunct problem
Hi,
The Predictor@home scheduling server runs as a C++ CGI program under
Apache 2.0.50 on Linux. The cgi processes are giving us a lot of
problems and cause a severe loss in performance. The cgi processes
defunct all the time and don't give back the allocated memory to the OS.
The cgi processes are about 2 MB in size and that's about the rate how
fast the phys. memory is decreasing. Then at some time stuff will be
starting to be swapped to disk and take down the machine and make it
very unresponsive. There are no signal handlers in the cgi code for
Linux to make sure the cgi processes don't become zombies and close in
a correct way (giving back their allocated memory).
Is it possible to configure Apache so that it catches SIGCHILD signals
and ignore them? Any help is welcome.
Thanks,
Michela
