Could it possibly be for communication with a DNS server ? Have you tried sniffing UDP packets
sent to/from this port?

Subject: [users@httpd] Apache listening for UDP requests?

While debugging an issue on one of my apache webservers with lsof, I noticed the following:

httpd     16679     http   23u  IPv4 0x30008c5fa88    
   0t0      UDP *:41034 (Idle)
httpd     16679     http   27u  IPv4 0x30008bf4d20    
   0t0      UDP *:* (Unbound)
httpd     16679     http   28u  IPv4 0x30009526088    
   0t0      UDP *:* (Unbound)
httpd     16679     http   29u  IPv4 0x300084f32e8    
   0t0      UDP *:* (Unbound)
httpd     16679     http   30u  IPv4 0x30009590e68    
   0t0      UDP *:* (Unbound)
httpd     16679     http   31u  IPv4 0x300094087f0    
   0t0      UDP *:* (Unbound)
httpd     16679     http   32u  IPv4 0x30008edf0d0    
   0t0      UDP *:* (Unbound)

What does this mean? Is Apache listening for UDP requests? If so, why?
