SCO Unix 5.0.5 freezing

Hie

I use SCO Unix 5.0.5 as my operating system and i have been having the following problem for the past couple of days :

After every 3 hours or more , my system freezes and all users are locked out .I can not do anything even on the console . Each time i have to press the reset button for it to work again .

My greatest fear is that , continously restarting my server abnormally will damage my data and my hardware .

Can anyone assist

Check this thread.

Dear,

go sysadmin without enter in multiuser mode (don't press ^D for sco 5.0.?)

and select software test and verify in all respect , then fix the problem

and i think you shoud run (pwconv) for user login/password file proper
