According to the findings in the post above I patched the socket.c this morning as follows:

Right now the server runs since about 08:00 am in the morning without any coredumps or other issues. No problem up to now. I know that this is more a dirty hack^W^Wpragmatic workaround but it seems to do the trick - at least for me and my configuration. t++ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
