we got bit by this on one of our high-load development servers. the DNS server hung, and all the webserver ground to a halt.
in 1.3 we had a custom module which tweaked the resolver's retransmission time interval & #times to retransmit options (in the global structure _res on most unixes) now the questions.. is this kind of thing available on win32/os2/beos etc? should this be a APR-function of just a auto-conf option? cheers Ian
