INVALID_PDU error on 4.5 GA

java.lang.OutOfMemoryError: Java heap space

There's your error. Tomcat's out of memory.

You should search for forums on increasing the memory heap for tomcat.

Before I had followed the advised as posted here from step 5, but only increased as suggested by 50, should I use bigger value?

5. as user zimbra, run

zmlocalconfig -e tomcat_java_heap_memory_percent="50"

6. ZimbraAdmin had some mail queue problems after that, error system failure: exception during auth
7. as zimbra, run

zmsshkeygen
zmupdateauthkeys
tomcat restart

works fine so far... except the pop3 mess of course.

Yeah.
How much RAM do you have? That may be the problem.

Increasing the memory by 80 solved the problem.

zmlocalconfig -e tomcat_java_heap_memory_percent="80"

Thanks jholder

U just saved me from 13000 students!
