We've had issues with firefox randomly crashing (ditto for thunderbird) 
that started shortly after the last pair of updates for both packages.

The redhat mailing list had some traffic about a user having bad 
performance with glibc on RH5 (as compared to SuSE and RH4).

We are running RH5 clients with all software installed locally and home 
dirs NFS mounted from an HP-UX box.
