System Analyser Execution graph for multicore

Hello all,

We are trying to get an execution graph of my application which uses Sys/bios and Notify (IPC) communication between 8 cores.
The application is functionnal (it works with and without SA).

Our setup:
EVM C6678 through JTAG
single image for all cores
Sys/bios 6.33.6.50
System Analyser 1.1.0.04
XDCtools 3.23.04.60
CCS 5.1.0.201206191800

CFG : see below

We use JTAG run mode. All 8 cores are instrumented.

The execution graph is strange and doesn't work as expected.

We want to see on it (for each core):
1) the time spent in the only task of the program
2) the time spent in the callback function registered with notify
3) flags when a notify event is sent

3 questions :

a) What does the Out_of_seq Data warning mean ?
b) Why is System Analyser so unreliable ? It's crashing the debug session everytime we change the slightest thing.
c) What are good starting points for the size of the sysbios loggers for an 8 core application ?

Thank you,
Clément
