Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am having the exact same problem as this old listing, which was never solved.

Apache intermittently aborting requests

if you go to the site below (all the sites on the server are having the same problem) and look at the net calls in firebug or any other browser you can see that intermittently some of the requests are aborted and sometimes the page fails to load completely:

ni##nesh##arp.co.uk

please remove hashes.

In the log files I can see that the file that end up being aborted are showing as a 304:

x.x.x.x - - [13/Sep/2013:11:12:15 +0100] "GET /images/white_logo.png HTTP/1.1" 304 -

I have tried restarting httpd and looked in the log files.

On restart my httpd error log shows:

[Fri Sep 13 11:18:43 2013] [notice] caught SIGTERM, shutting down

[Fri Sep 13 11:18:45 2013] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

[Fri Sep 13 11:18:45 2013] [notice] Digest: generating secret for digest authentication ...

[Fri Sep 13 11:18:45 2013] [notice] Digest: done

[Fri Sep 13 11:18:45 2013] [notice] Apache/2.2.15 (Unix) DAV/2 configured -- resuming normal operations

and in /var/log/messages im getting:

Sep 13 11:16:04 s16632747 rsyslogd-2177: imuxsock lost 170 messages from pid 1867 due to rate-limiting

Sep 13 11:30:58 s16632747 rsyslogd-2177: imuxsock begins to drop messages from pid 1867 due to rate-limiting

Sep 13 11:31:03 s16632747 rsyslogd-2177: imuxsock lost 89 messages from pid 1867 due to rate-limiting

Any help would be greatly appreciated.

Thanks

Ben

As a temporary / partial fix I have changed KeepAlive to On. This seems to work unless you do a CTRL+F5 to force a refresh. Presumably that would affect new users to the site? –  user1844937 Sep 13 '13 at 12:18
    
So what was pid 1867? –  Michael Hampton Sep 13 '13 at 14:52
