Subject [users@httpd] Return of bug 14219 in version 2.2.8? (too many SSL VHs causes fopen to fail)
Date Wed, 02 Apr 2008 17:43:52 GMT

On recently upgrading to 2.2.8, I was rather surprised to find that my
new binary would not start on the production server. The error message

[Wed Apr 02 19:25:18 2008] [error] Init: Unable to read server
certificate from file /path-to-certificates/cert99.crt
[Wed Apr 02 19:25:18 2008] [error] SSL Library Error: 33558552
error:02001018:system library:fopen:Too many open files
[Wed Apr 02 19:25:18 2008] [error] SSL Library Error: 537317378
error:2006D002:BIO routines:BIO_new_file:system lib

After trying all the usual suspects to do with increasing system
resources, I discovered that this was documented in an old bugzilla:

I commented out a few VHs and found that the problem only kicked in when
the number of VHs (hence log files) and SSL certs reached a certain
size. So it seems that the problem is indeed due to a file descriptor
exceeding 255, as the report describes.

The funny thing is, apache 2.2.6 starts perfectly when loaded with the
*exact* same config file (hence same number of files to handle)... So my
question is, does anybody know what has changed between 2.2.6 and 2.2.8
that could resurrect this rather limiting behaviour?
