I am also having an issue with mongrel becoming unresponsive.
Here is it's environment:
Red Hat Enterprise Linux ES release 4
ruby 1.8.5 (2007-03-13 patchlevel 35) [x86_64-linux]
Mongrel Web Server 1.0.1
In front of these mongrels, is Apache and the haproxy load balancer
I am running several different ROR sites on the same server.
after a few hours the rails application will become unresponsive.
My log file sings this tune:
Server overloaded with 5 processors (5 max). Dropping connection.

A restart of the mongrel, fixes it, but it doesn't last.
I have been trying to use the gdb to to gain some insight as the the root
cause.
Using the examples I found on the web,, the following was suggested
(gdb) set $ary = (int)backtrace(-1)
(gdb) set $count = *($ary+8)
(gdb) set $index = 0
(gdb) while $index < $count
> x/1s *((int)rb_ary_entry($ary, $index)+12)
> set $index = $index + 1
>end
However, I get an error on the second line
"(gdb) set $count = *($ary+8)
Cannot access memory at address 0xffffffff985779d8"
Has anyone seen this before?
Cheers,
Nathan C.
