Crash-dump using Windbg

I am working on a medical device running with windows XP embded. Recently a crash occured on the device when I was trying to access certain functionality in the device remotely. it generated minidump files and I am trying to analyse the cause of crash.

I completely new to windbg and trying to analyze the dump file. here is the output of the !analyze comand:

I could able understand that the code has failed in S14_RecorderManager module. Any input on this output to proceed further will be a great help.

Thanks in advance for any suggestion.
