Hi, More precisions : 1 - When I speak about fakesmsc, it is not the kannel fakesmsc, but a fake connection, provided by my real provider... (sorry about the vagueness in my previous mail). 2 - I was wrong telling that DLR was disappearing. Kannel logs shows the correct DLR's, but my MySQL database seems to be overloaded about few of them, and ignoring some DLR status (about 0.3%).
In fact, at this point, I have to change : DLR storage (nowadays internal, to MySQL-storage) And I guess my problems are probably not about kannel configuration (except the mysql-storage), but just mysql or apache configurations... And then, check again a 500K SMS campaign... But, If someone here has a 20 SMS/s throughput, I will be pleased to know the problems they encountered with high load during 7-8 hours... and the way they solved them ! ;-) Thanks for your answers, BR, Nicolas -----Message d'origine----- De : Nikos Balkanas [mailto:[email protected]] Envoyé : lundi 23 février 2009 21:31 À : Jovan Kostovski; Nicolas Dagnet Cc : [email protected] Objet : Re: DLR disappears ? Hi, Memory increase is not normal. Especially if not released afterwards. Using fakesmsc I have sent 1,000,000 PPGs (MT, similar to SMS) in ~12'. 1000 simultaneous requests at a time. No increases in memory. Unfortunately was trying to bench PPGs and therefore didn't bother to match DLRs. I have observed, though, that while using dlr-mask 31, I am getting usually both 8 & 1 dlrs, but a few times only 1 or only 8, despite that push has reached the mobile. This is indeed strange. You said you are using fakesmsc, and then that your provider sent you your DLR logs. How is this possible?

This is a normal behavior. Server crash? bearerbox crashes? > Does anybody have heard about the same DLR disappearing ? Just a wild guess: Maybe the system (OS or kannel it self) can not serve that amount of DLR responses simultaneously. Why don't you try with smaller throughput like 10 or 5 sms/s and see what's happening. Any other opinions/experiences? BR, Jovan
