Bugzilla database corruption in MySQL 3.23.51

[Eddie Xie]

My Bugzilla is using an old version of MySQL ("Ver 3.23.51 for
pc-linux-gnu on i686") I have noticed lately an increasing number of
index corruption problems.  Does MySQL have a reputation for this?  Or
are my databases just getting to big?

I guess the real issue is avoiding these index corruption problems in
the first place.  Would updrading my MySQL implementation help out
here?

Thanks!
