Mongrel Randomly getting TERM

Rails
1

Has anyone ever experienced this problem? Every 12-24 hours one of my
mongrel processes gets a TERM signal and quits.

There is all I get in my mongrel log…

** Mongrel available at 0.0.0.0:8003
** TERM signal received.

And my rails-log is silent too. No request starting. Just the end of a
successful request and then nothingness.

The other processes are doing just fine and stay up for good. Anyone
know
what’s going on here?

Oh yeah, and its lighty-proxy + mongrel on Ubuntu.

A few people have reported this, and the only time I’ve seen it was when
I ran under a Xen VPS and there wasn’t enough ram for the process, so
Linux went in and started killing processes at random. I believe it
does this if the CPU or memory gets dominated by a process, but I’m not
sure how to turn it off.

it’s probably something with ulimit or rlimit. by default, on the two
distro ive tried in the past 5 years, there are no limits, which means a
script can get in an infinite loop, chew up all RAM, chew up all swap,
then make the system entirely unresponsive with nonstop disk-grinding
until it is reset…

Hi,

I’ve not been getting a TERM signal, but I have been getting a random
HUP signal. It is still happening and I have no idea why. There’s a
thread from mid-June on the mongrel mailing list.

Cheers,
Bob
