Spawned ruby process by mod_passenger on apache 2 taking 100% CPU
 

Hi all,

I have installed mod_passenger on my Apache 2 under Debian Squeeze 64 bits.
My problem is that, just starting apache with mod_passenger enabled (no site configured to use it) spaws a ruby process that eats all available cpu.

I'm pretty sure this is a misconfiguration on my part, but I'm not quite sure where it comes from and how to track down the problem. It used to work perfectly and a some point it went wrong.

Any hint on how to identify the problem who be immensely appreciated !

Thanks !

I don't know if you should run Passenger w/o site configuration but there's at least one bug listed at http://code.google.com/p/phusion-pas.../detail?id=711 and there's a nice writeup on how to debug Rails processes at http://warwickp.com/2010/06/debuggin...er-with-nginx/ (never mind the Nginx part), the latter may help you ident the problem.

Solved
 

Hi,

Sorry for the slow reply and thanks for your help.
Running passenger with or without site config didn't change anything (there used to have a site configured, but I disabled it for testing purposes when I discovered the problem), but in fact, the problem didn't come from there.

I suspect it came from the leap second on June 30th that wasn't handled correctly for some reason by Passenger/Ruby.
In fact I found this thread describing the same problem I had.
The solution was "just" to reboot the server and indeed, it works now.

I still don't know where the real problem was though, but at least my server works.

Thanks again!
