Very recently, we migrated from DEBIAN 5(Lenny) to DEBAIN 6(Squeeze).
Since, our application is based on GTK 2.0 we thought migrating from GTK
app is pretty easy.
So, as a first step we compiled our application and ran some regressions
on the system.
Suddenly, we noticed application getting crash @
**libgdk-x11-2.0.so.0.2000.1**. This leaded system to crash at
unexpected state.
core sample info:
Program terminated with signal 11, Segmentation fault.

From the received **CORE** ,we were not able to conclude what is
causing the exact issue.
So, to fix this issue we ran various trials on the system and found that
when DEBIAN 5(lenny's) LIBGDK-X11( **libgdk-x11-2.0.so.0.1200.11
** ) and LIBGTK-X11 ( **libgtk-x11-2.0.so.0.1200.11** ) is used, the
system does not crash.
However, when we run the system with mention configuration, we notice
that **XORG** memory is increasing gradually and reaches to **SWAP** in
hours of time.

Request ,some debugging model to understand and fix the root cause of
the issue.
