Re: Index Issues & ReIndex

Tom,

We have tested our ram, and our previous build has the exact same hardware which is stable but this does not rule out
hardware. I lean towards software to the fact that we are only finding the instability in the indexes.  The four
millionrows we write per day are perfectly fine, but just cause huge 6 gig processes randomly from the index being
brokendown.  An hour long reindex usually fixes it until we insert more items. 

We do get resulting errors like "root page level 1 expected 3" some times on the index as well.  Reindex fixes it.

We're running Gento which was just compiled 1 month ago up to date with a just brand newly compiled C compiler.

Thanks,

Andrew
