I had two servers load balanced through Apache and mod_jk (virtual machines) A and B which both were running Centos 6.5 but later we moved server A and B to physical servers and next we moved the contents of server B to a physical server too.Then we started getting strange bugs and errors like the application running not being able to find some java code and etc. while before moving the vm to physical was fine.So I checked the and realised that the technician responsible for OS installation had installed Centos 6.5 on Physical machine A and RedHat on Physical Machine B and I did not realise it because of the both OS being too similar.Could the problem be because of two servers running different OS or because of some configurations?
