Our center of attention is ServiceToService.setClientLoggingInResponse() method (which is called from RequestProcessor class line:12) . I have log printing the following output from bottom to top. We see memcache error on third logged statement. It occurs in MCache.readFromCache() method then it goes to catch block of RequestProcessor class (line 15 of RequestProcessor class). I am unable to comprehend why it is in catch block of RequestProcessor. Because I thought I have everything cover in setClientLoggingInResponse(). I thought if memcache error arises it should go to line 48 in setClientLoggingInResponse() method. But as log shows it didn’t. I have two questions.

I am in dire need of help. I dont know when this error arises as I am unable to reproduce this bug on my own.
