I have recently come across an issues where I ran out of file handles and couldn't open up any files. This is, as you know a mod_perl Apache::ASP based application (don't flame me, I didn't start it, just just support it........). The problem occurs on Linux (2.6.9 - RedHat EL4 update 2). Vanilla Perl 5.8.7, apache, mod_perl, mod_ssl install. These binaries are separate of the base directory structure
The very same application works fine with default apache 1.3 server tuning on Solaris 8. We are in the process of moving these applications to Linux. For the most part the software versions are the same on both platforms with exception of the minor versions.
here is a few lines from lsof that look to be eating up the filehandles and not releasing them:
httpd 17196 nobody 93u sock 0,4 11020434 can't identify protocol
httpd 17196 nobody 94u sock 0,4 11020606 can't identify protocol
httpd 17196 nobody 95u sock 0,4 11020717 can't identify protocol
I have the MaxRequestsPerChild set to 5000. This seem to control things at an acceptable level of file handles by killing off processes, once killed off, large blocks are released.. The apache processes do not look like they make it over 60meg in size either.. But this isn't the right way to do this I'm sure. ideas?
