Reseat = take it out and put it back in again.

The ecache glitch is a known problem with UII 400MHz processors. If you have
the latest patch kits for Solaris there are workarounds for the design flaw
which causes the crashes.

Hi,

We got an Ultra 5 with an UltraSparc IIi 400 Mhz processor running Solaris 8

64 bit with kernel patch 108528-05 installed.

It's rebooting itself at least once a day. Sometimes the reboot is
successful, 
other times it doesn't come back up.

A quick look in /var/adm/messages tells me that we are getting kernel
panics.
There is also the following message:

[AFT1] Ecache Tag Parity Error on CPU0 Data access at TL=0

The machine is a test box running Netscape Web Server and Weblogic App
Server.

I can't find any patch info from Sun's website regarding this error. The
only 
advice I've had is to either reseat the CPU or to replace the CPU.

Two questions:
Is this my only option?
How do you reseat a CPU?

Thanks,

Andrew
