We are using Novell version 6.5 installed on HP Proliant ML350G5 server configured for RAID 5 since 2005 without any trouble. However recently we are facing problem that server automatically get restarts. Some time restart may occur twice or thrice in a day. Sometime not at all for 4-5 days. We are using In house application developed in Visual Foxpro 9 and using since 2005 without any trouble. Mostly it has been noticed that server restart occurs mostly in the morning session. Morning session most users are attemp to logged to server to start working. One thing is to be notice that there is no dabtabase (.dbf) corruption ocures if server restart.
