Failed hardware in /var/adm/messages and Interleave Way?

Do I have a memory/bus issue?

Thanks

this is an enterprise server... open a call at the sun support hotline! seems like:

Corrected Memory Error on /N0/SB4/P1/B1/D1 J14401 is Persistent

a dimm has failed a needs replacement...

It seems like DIMM memory error

hmm looks like ECC memory problems. If these errors are repeated and span few pages in messages then time to call up sun. Otherwise just leave it if these errors are only on a few lines and happen a few days(or weeks) ago.
