Making sense of stacktrace

I have been trying to debug an issue with my service which results in a segmentation fault. I do not have access to the production server, so I have handled the SIGSEGV signal in my service and printed the stacktrace in the Log files. Following is the stacktrace when the service crashes

However, this trace is not of much use as I cannot pinpoint the location in my code where the issue is occurring. Can somebody help me better understand and inspect this stacktarce. Thanks
