This is the first time I post to this group. I don't know how much
info I should provide so that you can help us to debug. I just put
what I thougth would be relevant. If you need more info, please let me
We are running Rails 1.1.6, Lighttpd, on a Fedora 5 box (MySql is
running on a separate box),
Linux app 2.6.18-1.2257.fc5 #1 SMP Fri Dec 15 16:07:14 EST 2006 x86_64
x86_64 x86_64 GNU/Linux
Before, we used backgrounDrb 0.1.x version. After frequent high CPU
usage (>90%), we recently upgraded to 0.2.1 version. Now the average
CPU usage is normal (around 20%), but sometimes we see more than one
backgrounDrb main process hanging on. Those stale processes were still
there even after running backgroundrb stop. So we have to manually
kill those old processes.
Another scenario just popped up. While everything seems fine on the
Linux box, CPU, processes, etc., the site just cannot be reached.
Sometimes we can still SSH into it, sometimes we cannot so had to cold
reboot it. When we can still SSH in, we just run backgroudrb stop.
Manually kill the /tmp/socket file sometimes. Then run backgroundrb
start again. The site will behave normally.
Below is from our config file for backgroundrb :
