Re: Out of memory with Java 1.5 and 2.6.11.6

The oom-killer a piece of code which starts killing processes when you
run out of memory. OOM-killer = Out Of Memory Killer. My guess is that
the second jvm consumed all the memory left ( this may me be a memory
leak, if so report it to SUN, not lkml ) and eclipse , being a
memory-heavyweight got slaughtered. The first thing that came to mind :)
