Hi Mathieu,
Thanks for the reply ... am using lttv version : 0.12.36, which is
compatible according to the compatibility list.
Also, one more thing what i observed is if i do not enable the statedump, i
am able to get the trace dump, which i can view in lttv-gui.
But that doesnt give any details on the process name ...
Is there anything i am missing ??
I followed the foll procedure :
1. downloaded and patched the lttng 0.232 version on 2.6.35.7
2. built the kernel and lttng modules and the ltt-control modules.
3. installed the modules on target.
4. then loaded all the required modules
5. started ltt-armall
6. exported the lttd path
7. then executed lttctl to create trace
8. after collecting the trace (without statedump) from the target onto my
pc,
i am able to view that trace in lttv on my computer.

Probably that the statedump module was buggy in that lttng-modules
version. You might want to try a newer release.
