Comment 1 Jeff Trawick 2003-10-10 12:31:41 UTC
Resolving the problem that caused the cgid daemon to exit: The upcoming 2.0.48 resolves one particular bug that can cause the cgid daemon to exit on Solaris. Please let us know after moving to 2.0.48 whether or not the cgid daemon still exits intermittently. Recovering after such a problem: The patch below causes the cgid daemon to restart automatically after such a problem. The patch has been committed to Apache 2.1-dev but not yet merged into the stable tree because it relies on a behavior specific to the worker MPM. I would not hesitate to use the patch on Solaris with the worker MPM though. This should resolve the long-term affects of whatever problem causes the cgid daemon to exit. http://cvs.apache.org/viewcvs.cgi/httpd-2.0/modules/generators/mod_cgid.c.diff?r1=1.151&r2=1.152
Comment 2 Joel Parramore 2003-10-29 12:54:00 UTC
Should that patch be used on top of 2.0.48, or is that change already in 2.0.48?
Comment 3 Jeff Trawick 2003-10-29 13:00:46 UTC
The patch is still not in stable branch (2.0.x) because it has an inappropriate dependency on some behavior of the worker MPM. If you can't get the patch to apply to the latest mod_cgid from stable branch, let me know and I'll post a new one.
Comment 4 Jeff Trawick 2003-12-13 22:28:04 UTC
patch pointed to previously is still appropriate for use with stable branch this problem was fixed in Apache 2.1-dev some time back with PR 19849, but a couple of issues prevented it from being merged into stable branch... those are now resolved, so hopefully the fix can appear in a 2.0 release before too terribly long *** This bug has been marked as a duplicate of 19849 ***
