I have recently deployed a number of CentOS-3.4 boxes and I am seeing problems with rpm database apparent corruption. db4 errors like DB_PAGE_NOTFOUND. I have found that using LD_ASSUME_KERNEL=2.2.5 seems to fix the problem but I can''t find much info on why or if doing that is good or bad. I have done --rebuilddb but with the LD_ASSUME_KERNEL that might be making thinks worse... I just don''t know. Does anyone here know anything about this problem?

Once you''ve gotten over the leap to a 2.6 kernel, some problems should just go away. I''ve gotten quite good results with 4.0_rc1. Sorry, not really an answer, just a suggestion. -- Collins
In answer to my own question, this is what I have done which appears to fix the problem: 1. Edit /usr/lib/rpm/macros and change the line %__dbi_rebuild nofsync !log !txn !cdb to %__dbi_rebuild nofsync !log !txn !cdb !thread 2. export LD_ASSUME_KERNEL=2.2.5 3. rpm --rebuilddb 4. unset LD_ASSUME_KERNEL 5. Edit /usr/lib/rpm/macros back to the original 6. rpm --rebuilddb So far this fixes the problems I have been having. I assume it is possible to override the macro setting on the rpm command line so no editing is required and a simple script can be run on all my machines. John.
