--------------------------------------

Hello,

I have followed Bjorn's advice and updated AIXS from 1.2.1 to 1.4 but the problem still exists.
The out of memory occures exactly at the same line.

>    Affects Versions: 1.2

> After undetermined time (3 or 4 days) the java client crashes with an out of memeory
exception. Analyzing the head dump showes that during the deserialization the SAX2EventRecorder$objArrayVector.add
 produces a huge amount of MessageElemets. The returned message is a 3times nested array containg
in the inner arry just a strings [ [ [ key~value, ..., key~value ] ] ]. Here a snippit of
the array
