In our project we are using Ittiam provided audio encoder which is codec engine API based implementation.
It contains sample application for audio encoding.
This application is running fine. But not always. Sometimes at exit of an application there is large carsh coming at the end.
Crash show that it is coming from syslink driver.

Due to this crash board hangs after that only power cycle reboot is an option. This issue is very critical.
Please find the attached crash log for your reference.
We are clueless about this issue and not sure how to debug this issue.
Any pointers or help regarding this issue will be appreciated. Let me know if any logs or more information is needed.
Thanks,
Jemish
