Unfortunately this isn't what I'm seeing on my Red Hat Linux 8.0 web
server. My site gets very heavy traffic and often hits the 2GB limit
with access log. A few times I noticed my site stopped responding and
when I look at the processes I see this:
PID TTY STAT TIME COMMAND
1 ? S 0:39 init [3]
1836 ? S 1:10 syslogd -m 0
1879 ? S 1:39 sendmail: accepting connections
1888 ? S 0:00 sendmail: Queue runner@01:00:00 for
/var/spool/client 1920 ? S 0:01 crond
9754 ? S 1:06 /usr/sbin/httpd
30692 ? Z 0:31 [httpd <defunct>]
21284 ? Z 0:32 [httpd <defunct>]
8589 ? Z 0:32 [httpd <defunct>]
28034 ? Z 0:34 [httpd <defunct>]
28154 ? Z 0:32 [httpd <defunct>]
32331 ? Z 0:37 [httpd <defunct>]
6490 ? Z 0:31 [httpd <defunct>]
1844 ? Z 0:34 [httpd <defunct>]
23605 ? Z 0:30 [httpd <defunct>]
Strangely it sits in this state for a few minutes, sometimes up to an
hour, and sometimes recovers on its own with all httpd processes happily
serving again. Several hours later it fails again in this manner and
repeats.
How reproducible:
Always
Steps to Reproduce:
1. Fill up 2GB log file with Apache 2.0.
2. Pound it with constant moderate-heavy traffic.
Actual Results:
httpd failure with bunch of child zombie processes. Somehow recovers on
its own. Fails and recovers repeatedly.
Expected Results:
Shouldn't fail at all.
