We have 3 server, 2 IBM x345 and 1 INTEL
We upgraded them to 6.5 sp 3 and update them with the following patches
Nw65sp3ncp.exe+ns65sp3a.exe+iprintjar3.exe+cnmgrsp 3.exe+n65nss3a.exe

The server where up for 2 weeks, then we had to restart the 3 server,
after restarting all of them hangs (not abend) every time in another
place in the autoexec procedure,
If we start the server with na it starts fine ,but when we apply the
It hangs without any message and every boot the servers hang in another
command so we can not trace which command is causing the problem
Waiting for help we are down
