OK, I understand what you're saying about Multicast, thanks. Then, let me turn to the 2nd paragraph. Perhaps coincidentally, around the time I began ingesting said data on Multicast, I began noticing "bind:address already in use" errors when restarting services that bind to particular TCP ports--such as 4559 (hylafax). The only way I've found thus far to restart the services without the bind error is to reboot. What can I try to fix this? Could it somehow be due to the Multicast feed? I don't see how, but the coincidence is very hard to ignore. Thanks, Kevin --------------------------------------------------------------- Kevin Tyle <[EMAIL PROTECTED]> MESO, Inc.
