#1 JVM core dump

[Riadh Elloumi]

The java process of the image filter craches when it
gets the first image and displays the message below. I
expect that it happens when the JVM is loading the
dynamic libaries but I cannot guess what is the problem
exactly... The monitor also dies because it depends on
the connection with the image filter.

I forgot an important detail: this crash happens only the
first time I lauch poesia after the Linux boot. In the
following times, Poesia works well ! I think that's because
Linux loads partially the needed libraries in the first time
before the crash, and after that the loaded libraries remain
in the memory. In the second time, Linux loads the remaining
libraries and that works well because some dependencies are
already solved...

The problem seems to be outside the JVM, because I updated
the libraries used by the image filter (Netpbm and GTK), and
the problem disapeared.

Sorry, it does not really disappear. May be upgrading the
JDK will solve the problem?

When I upgraded to a 2.6 linux kernel, the problem
disapeared actually!
