That is a four year old version, which has seen three new major versions in between, so it is definetely not supported anymore. Any possibility for upgrading in sight?
I'd be a little surprised if that is all the loglines in question, as the first line states, that this was a nested throw (unless that exception occured many times over in the running JVM).
Are you using long scripts in your queries? Apart from that I don't have too much other ideas and given the age of your version I don't think debugging further makes a ton of sense as I don't remember a lot of the nasty details from a long time ago...
