COuld not telnet but server powered

Hi

We are running SCO unixware 7.1.1. I am new to unix so hope someone can help.

This morning no one could log into the unix server by ssh. Server could not be pinged but the server was powered. We could not also view the screen.

We have to manually power it down and it came back up.

I read somewhere that if the tmp gets full this may causse problems. Would this cause for people not to be able to login to the server?

this is status at the moment

/tmp : Disk space: 148.76 MB of 150.00 MB available (99.18%)

when viewing files in tmp directory i can only see 9 files but doing a ls -l says that there are 88 in total

please can someone advise?

regards

tj
