mysql timing out... errors 10048 and 10061

hi,

i installed a phptracker with a mysql database behind it... everything works pretty fine except after a few hours my database begins giving white screen witht he 10048 or 10061 errors...

i know that it are not the processors (using a dual processor server) because they never peak... they always stay around 50%cpu time...

the bttracker is working with maximum 1600 peers for the moment... so this can not give that much traffic...

the strange thing is that it seems too happen every time when my virusscanner is finished... virusscanner is a norton corporate 8...

this is my "my.ini " file from the mysql database

i know he is a bit big but i took the "hughe" setting from the mysql source and adjusted it a bit ... maybe there are mistakes there??

can my slow internet connection be a problem?? serving this on a ISDN alike line (115.5 Kbits/sec)...

thanks for any advice to this mysql newbie
