EMLINK (Too many links)
Hi!
Yesterday i migrated an old webserver (Apache 1.3.34, FreeBSD
5.2.1) to
Apache 2.2.3 and FreeBSD 6.1.
The configuration consists of 776 vhost.
After importing the vhosts.conf file i did a apachectl
configtest and it showed no errors.
But with apachectl start i get an segmentation fault.
Did you recompile all the modules you are using against the new apache?

Yesterday i migrated an old webserver (Apache 1.3.34, FreeBSD 5.2.1) to Apache 2.2.3 and FreeBSD 6.1. The configuration consists of 776 vhost. After importing the vhosts.conf file i did a apachectl configtest and it showed no errors. But with apachectl start i get an segmentation fault. Did you recompile all the modules you are using against the new apache? Rgds, Owen Boyle Yes this is a new install out of the freebsd ports.

Versions of OpenSSL older than 0.9.8c can crash when reading from the random device on some platforms when the fd number returned by open has been pushed above the FD_SETSIZE setting. If that's really the cause then there are a number of possible choices: 1) disable mod_ssl 2) recompile OpenSSL with -DFD_SETSIZE=4096 if the platform allows this 3) upgrade to a newer OpenSSL joe - The official User-To-User support forum of the Apache HTTP Server Project.

I disabled mod_ssl and apache starts without a segfault. Thx! Alex
