Subject [users@httpd] apache-2.2.15 on mac os x snow leopard: could not lookup DNS configuration info service: (ipc/send) invalid destination port
Date Thu, 25 Mar 2010 17:46:40 GMT
dear community,

httpd behaves pretty strange on my mac installation: i am serving a cgi 
script and everything works ok after starting the httpd (e.g. from the 

xx.xx.xx.xx - - [25/Mar/2010:18:15:50 +0100] "GET /cgi-bin/ 
HTTP/1.1" 200 29 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; 
en-US; rv: Gecko/20100316 Firefox/3.6.2"

but then, some time later, the cgi script is no longer available, 
instead i find this in the error_log:

[Thu Mar 25 18:02:44 2010] [error] [client xx.xx.xx.xx] could not lookup 
DNS configuration info service: (ipc/send) invalid destination port

a restart of the server fixes this, but only for a short while.

could somebody guess what causes this?
help would be greatly appreciated. TIA, chris.

here some things i tried for diagnosing this issue:

*508 moria ~ $ hostname

*509 moria ~ $ ping localhost*
PING localhost ( 56 data bytes
64 bytes from icmp_seq=0 ttl=64 time=0.039 ms

*512 moria ~ $ sudo  apachectl -S*
[Thu Mar 25 18:16:31 2010] [warn] module php5_module is already loaded, 
httpd: Could not reliably determine the server's fully qualified domain 
name, using moria.local.pc for ServerName
VirtualHost configuration:       is a NameVirtualHost
          default server 
          port 80 namevhost 
          port 80 namevhost 
          port 80 namevhost 
Syntax OK

My setup:
