Apache 2 in 6.0 jails: Connection refused: connect to listener on 0.0.0.0:80

[Philippe Lang]

Hi,

Every now and then, Apache 2.2.2 starts filling my httpd-error.log with thousands of lines like:

[Sat Jul 08 20:57:32 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80
[Sat Jul 08 20:57:33 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80
[Sat Jul 08 20:57:34 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80

[Sat Jul 08 20:57:38 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80
[Sat Jul 08 20:57:39 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80
[Sat Jul 08 20:57:40 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80

I'm running Apache in FreeBSD 6.0 RELEASE-p2 jails.

Restarting Apache cures the problem for some time, until the problem appears again. It is not that frequent, but the servers are not much loaded either.

I think I saw this problem appear with Apache 2.0, 2.1, and 2.2, so it's apparently here for a while. And others had this problem too:

http://groups.google.ch/group/lucky.freebsd.apache/browse_thread/thread/7a5735ae7a3a4c2d/e2d0d9ba4ad7266e?lnk=st&q=Connection+refused%3A+connect+to+listener+on+0.0.0.0%3A80&rnum=1&hl=de#e2d0d9ba4ad7266e

I'm pretty sure this problem must be BSD or Jails specific. Does anyone have the same problem, or maybe a workaround? Note that Lighttpd NEVER had this problem on this server.

Cheers,
