Whilst writing some unit tests I hit the upper limit for too many open files (Debian VM) - "failed to open stream: Too many open files"
Other than a restart, is there any way to clear this block? (i.e. will these open, but unaccessed, files be cleaned up over time?)
Fyi - I'd like to know because I want to setup a continuous integration server for unit testing, and if a reboot is the only way to clear this problem then I need to find a different way of approaching certain unit tests.
I've hit a wall whilst setting up a site using nginx / fpm. The page displays "File not found", and this appears in the nginx error.log:
FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream
I'm new to both nginx and fpm, and that error message means nothing to me (even the google machine hasn't helped!). Can anyone shed any light onto what could be happening?
I'm taking my first steps into the world of un-managed servers, and have confused myself whilst reading through the 101 tutorials on server hardening that Google spews out!
The most recent advice I have been given is to install both CSF and Bastille on my server (used to serve a consumer-facing ecommerce site and act as the business' email server), but my understanding was that both of these tools were an abstraction layer above netfilter / iptables. Will installing both packages cause any conflicts, or do they play well together?
I'm trying to install rkhunter via yum on CentOS 4.8, but it's just not happening...

I know some sysadmin basics, but not enough to problem solve when things don't go according to plan, and especially when Google doesn't want to give up the goods! Any help would be fantastic.
