termination

Hey guys, Im one of 3 owners of a gaming network which run a big tekkit server with over 60 people. We seem to be having a problems and Im just wondering would this cause it. Problem: We run a 3.1.2 tekkit server and what seems to be happening is my collegee is installing CB 1.3 plugins on this server that are designed for craftbukkit 1.3 not 1.2.5. Now could having over updated plugins on this server cause my server to crash. What happens there will be certain times where it will just kick everyone (Not show any errors) and then just show: TIME - [iNFO] - Read Timed Out And it will just repeat the line over and over and over again. Because tekkit 3.1.2 uses the bukkit build 1.2.5 would using plugins updated for 1.3 be a problem. Any feedback would be great.
