On one of my Netware 6.5 servers last week users could not login. As users tried to login the login script was stuck on attaching to server XXXX.

On the server console the users who were attempting to login all had the same file open:_netware:65.nds . The server Utilization was stuck at 39%.

I tried to clear connections to users who were stuck, but the connections would not clear. So I was forced to re-boot the server before I could really analyze it. When I downed the server it locked up. I was forced to go to debugger to finnally take it down.

Any ideas on what could have caused this?
