Hi
I am seeing DFB apps (df_andi or df_matrix) deadlock conditions with DFB 1.4.3
lib on linux 2.6.34 and seems all of the processes go in sleep state.Sometimes
it comes very soon.
I ran fusion /cat/proc interface stat , property and skirmishes command and see
in an output of /proc/fusion/0/stat lease count> cede count AND prevail>
dismiss .
Also if I look at cat /proc/fusion/property and /proc/fusion/skirmishes output
its shown locked by current process.
Could anyone please confirm me if its clear indication of deadlock so that I
can be confirm if am debugging in right direction and will help if you could
give some description of same .How can I debug it where it can get freeze?I
enabled FUSION_DEBUG_SKIRMISH_DEADLOCK but still I don't see any message on
console once deadlock is reached.
