Apache looping?

Apache looping?

Hi folks,

  I've discovered this morning that one of my web servers was
unresponsive. I check with a 'ps -ef' and discovered I had only one
httpd process (the parent, running as root). So, I restarted Apache with
'service httpd restart' and see the same behavior - parent is started
with no children. The access.log and error.log appear normal.

Nothing has changed on this server in months and I can confirm via the
previous access logs that it was responsive a couple days ago.

If I use 'strace' to attach to the running parent process I see this:

times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351
times(NULL)                             = -2088278351

The number is decrementing as it goes by (about once per second, which
probably makes sense).

I've tried using the default httpd.conf that comes with the package, but
I see the same behavior.

In addition, I updated to httpd-2 (See http://tpd-2.ora-code.com).0.46-56.ent.i386.rpm and
mod_ssl-2 (See http://ssl-2.ora-code.com).0.46-56.ent.i386.rpm (from 2.0.46-54.ent) and still no change
in behavior.

If anyone has ideas I would appreciate it as this server has about 10
websites it serves that are currently (obviously) out of the water.

Thanks,

Kevin
