It's like a directive from God :P "Don't fix it if it ain't broken!" Repeat it several times and _dont_ do this again. Lets look at the facts: Fact 1: Old Server ran PHP4, MySQL4 Fact 2: New server runs PHP5, MySQL5 Fact 3: App was probably coded in the PHP4 environment ( this is actually an inference that I'm making out of your statements ) Fact 4: See [1] Fact 5: PHP5 breaks many PHP4 apps :P Fact 6: MySQL5 also is responsible for breaking stuff coded for MySQL4 ( please read the release notes for further info ;) ) I hope you can understand what I'm getting at. Your app is probably behaving weirdly because of the incompatibilities between PHP4 and PHP5. I suspect MySQL ain't the source of the problem. Now, a personal note. Take this as constructive criticism. Next time you guys get the itch of upgrading stuff, please set up a box and test your upgrades. If not that, atleast read the release notes of the softwares whose major version numbers are changing ( PHP, MySQL, RHEL in this case ). It'll give you a clue as to what you might expect. I really feel you should downgrade to your older configuration. I seriously dont understand why everyone wants bleeding edge stuff? RHEL3 is properly supported by Redhat. If you can't afford the support, install CentOS. Geez what were your seniors thinking??? :O [1] -> -- Regards, Dinesh A. Joshi
