[Sunhelp] Sporadic reboots on Sparc 5

[S Condit]

Hi All,
	I've enjoyed reading the list over the past few months and I've learnt 
quite a few things - hopefully someone can help me out with this one.

We have a sparc 5  that we use for sendmail and apache (mainly). The 
machine was to be replaced by an Ultra5 before Christmas but the new 
machine wasn't ready on time. We had to apply the patches to Solaris 2.5 
(recommended and y2000 - we left out sendmail - openwindows - all the stuff 
we don't need) in a bit of a rush and ever since this the machine has been 
reboting on an irregular basis every 2-6 hours.

/var/adm/messages refers to kernel read and write errors at the time of the 
crash
pid varies - sometimes its a httpd process, sometimes sendmail, sometimes a 
system process.
It does consistently say 'Invalid Address on supv data fetch'

I've tried reapplying the patches, which didn't help.

Since all the messages refer to bad data there is a possibility that it 
could be hardware but as the reboots started just after the patches were 
applied, I would find this unlikely.

Any of you have any thoughts on this - apart from going to the backups :-)

TIA
