...or can you add the forge logfile for us to have a look at it.

Depends on the mods you want to add. If you can give me the downloadlinks i can see if i can pack them together for you including the configfiles to get around id-conflicts.

Try updating to the newest version of Java. Appears that you are running a unsupported version of java. 2014-03-08 15:10:38 [INFO] [STDERR] java.lang.UnsupportedClassVersionError: mrtjp/projectred/compatibility/CompatibilityCorePlugin : Unsupported major.minor version 51.0

Any launcher-logfiles to have a look at? have a look at %appdata%/.technic/logs/ to see if you can post the latest logfile.

I'm having the same issue on my server. Pipes allow small interactions with inventorys but requesting more than 2 stacks cause the whole server to "go to sleep" No crash or anything obvious in the forge-logfile. Just a non responding server... Removing all requestpipes seems to solve this. But placing them again causes the same error over and over...

Would be hard for everyone to know WHAT is not working for you. Do you have a crashreport or a forge-logfile or anything related to your problem that helps to solve it?

You are running an older version of Java. Try updating to Java 7.
