I maintain a network with a linux Redhat 6.0 server running Samba 2-0-6 and with Win95 and Win98 clients. The network connection to the Win95 clients crashes when copying large files (say 40 Mb) or when running programs that write similar large files. The error ONLY APPEARS on the Win95 clients -- the Win98 clients do not experience the problem. Nothing is written in the samba log during the crash. If I increase the debug level to 5 or above THE PROBLEM DISAPPEARS! Inspired by advices from David Collier-Brown I have tried increasing the oplock break wait time parameter up to a value of 4000 (!) without any changes. Please! Any suggestions are appreciated. - Carsten
