The problem is in FF consuming all available memory on the client for pixmaps.
In LTSP 4.2 X startup scripts there was a code that limited the X server memory to what was actually accessible by the thin client. This code made the X server stable because otherwise once the FF consumes all available memory and swap, kernel kills the X server and consequently the whole session. I do not understand why is this code not available in ltsp-5. It was very useful thing! With the X server being limited, the worst case you could face was that FF crashed - but the rest of the session survived! Increasing the swap is not a solution - bring the code I mentioned back!
