You generally can just call the method, there should be no "leakage" because you are not reloading the module just accessing one of its attributes - the method. Restart from the calling function not from the method itself of course! Thus you need a try/except in the driver section of your code and you need to do a raise in the implementation section after writing to sys.stdout... > Driver Section: > ap=apacheModule.apacheModule(configXML,putInDB="1") > while 1: > rVs=ap.perf() > for anObj in self.objList: Not sure what the last line signifies but you need to wrap the call to perf() in a try/except (if its perf that is failing - its not totally clear where the crash occurs). > Class Section (apacheModule module): > > def perf(self): > <..stuff deleted..> > self.putMethod: This is nonsensical syntax wise I have no idea what you are trying to suggest. Is it a call to self.putMetthod()? Or is it a branch: if self.putMethod: I'm assuming an if statement given what follows... > # putMethod is a variable controlled by an XML file, > assume > this is always true > return self.put(self.parse(lines)) If its put() that fails you could put the try/except here instead of the driver section. The question is whether you have the information needed to repair the damage or move onto the next data item(aka datum)? > else: > return self.parse(lines) > > def put(self,rVs): > <..stuff deleted> > try: > > (totalAccess,totalTraffic)=(rVs[3][1],self.sizeConvert > (rVs[3][3],rVs[3][4])) > > (userUsage,sysUsage,cuserUsage,csysUsage,cpuLoad)=(rVs[4][1],rVs[4][2],rVs[4][3],rVs[4][4],rVs[4][6]) > (requestsSec,bandwidth,perRequest)=(rVs[5][0], > self.sizeConvert(rVs[5][1],rVs[5][2]),self.sizeConvert(rVs[5][3],rVs[5][4])) > (requestsProc,idle)=(rVs[6][0],rVs[6][1]) > except Exception,e: > datetime.datetime.now() > sys.stdout.write(str(e) + "\n") > sys.stdout.write(rVs) > <..stuff deleted..> You need to add a raise here to force the exception up to the next level of detection.
