Loosing connections during large Copy

By Erle Williams ·
On a Netware 4.11 server (Netserver LH4) if the administrator uses Ncopy to copy a large amount of data (200MB or more) from one netware drive to another, users (including the administrator) loose their connection to the server. This problem is easily reproduced. Server is running 100MBps Full Duplex. Clients are mostly 95/98 with the netware client. Has anyone run into this?

Loosing connections during large Copy

I have this once before and it was due to a compressed volume that reported enough free space but when copying lots of files all at once it didn't have enough free space to uncompress them and it lose all network connections. I had to copy folders individually to get round the problem. Also corrupt files can cause the same problem so check if it always gives up on particular files, if it does then exclude them and see what happens.

I do not agree with any of the previous answers.
No matter if it is the same server or not, the problem is how netware works!. The major problem is that netware, believe it or not!, is not multi-thread. Netware will try to "finish" the copy (thread) before paying attention to another tasks (threads). There's no TIME routine for threads executions. That?s why some wks may loose it's connection to the server. More longer files causes more loose connections.
Recommended actions:
Install spack 7a
Set client presist connection to a higer value
Have ipx/spx installed and working
