[6.3.5] Help with deciphering Call Trace

[Farrukh]

Hi,

 

Can some help me decipher the following Call Trace? I am guessing that this maybe related to memory just from looking at the messages. I have attached the diagnostics.zip file for more system information.

Any help would be greatly appreciated. Thank you.
