did you start the telnet from the assp system to 208.69.48.43:125?

Seems your OS was going crasy. The maximum time used for a poll cycle is 
exactly one second. The call to the OS-poll call is out of our controll.
In human words assp and perl are telling the OS: tell me all registered 
sockets that could be handled by me now (read/write) - do this as fast as 
possible, if at least one socket is available or there are sockets in an 
error condition - otherwise you should wait, but to a maximum of one 
second.

If the worker knows that he has also some other work to do at this time, 
the max-wait-time is reduced to some microseconds - which was the case in 
your example.

So, if the call to poll takes ~29 seconds - the OS has taken this time for 
any of 1000 reasons.
In the past I saw this behavior in case of a NIC reset or switch error - 
or if all cores were running at 100% because of an overload (caused by any 
application).
