Dear all,
I have been trying my system with the patch Rene sent me a couple of days ago. In the begining I was getting the same very slow sms reception from smppbox and the same error messages about the broken pipe. Then I changed the behavior of my smpp client and got rid of the diconnections and reconnections. My client was staying connected all the time. I also limited the speed of the upstream bulk sms messages to my smppbox. And there it was, it got fixed. I finally got rid of the broken pipe error messages and my system was working just fine. Then, I tried to increase the upstream speed of sms to smppbox and there was a point when kannel/smppbox couldn't handle the speed anymore and my system got stalled a lot again. What I figured out was that my client was just throwing the bulk sms messages to smppbox and my guess is that smppbox/kannel couldn't handle the speed any more. That's why it could handle the low speed just fine. I am still confused a little but it seems my smppbox/kannel is finally working ;). I hope this thread is of some help to the users Thank you all for your kind help Cheers, Davit From: [email protected] To: [email protected] Subject: FW: smppbox bulk sms: slow reception from a client Date: Wed, 18 Aug 2010 17:56:50 +0200 Sorry, forgot to copy the list: Yes, if your problem is that open smppbox stalls every 10 messages, then I found it. If you want, apply the attached patch to smppbox and try again. About broken pipes and PDU unpacking failed: I have not been able to reproduce this as of now. I tried to submit 10,000 messages and no sign of any problem. To be continued. == Rene From: Davit Mirzoyan [mailto:[email protected]] Sent: Wednesday, 18 August, 2010 17:26 To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client Dear Rene, Hopefully the problem you found was the problem I encountered ;). Just to say, my smppbox/kannel stalls for definitely more than a second. Did you also get the same error and warning messages such, as broken pipe and PDU unpacking failed? BR Davit From: [email protected] To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client Date: Wed, 18 Aug 2010 15:58:46 +0200 I did find the problem why open smppbox would send 10 messages and then stall for a second. Thanks to Nikos fakesmpp stress test, I could isolate the problem quite quickly. Updated code will be available after next open smppbox update (see other thread of Victor Luchitz). == Rene From: Davit Mirzoyan [mailto:[email protected]] Sent: Wednesday, 18 August, 2010 11:42 To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client I am using ALT.SMS.SmppClient. It connects to my smppbox over smpp protocol and tries to inject bulk sms. Then it disconnects and connects again in a while for deliveries. Do you think it can be from my smpp client? It works fine when I send only a single sms through kannel/smppbox. When I have more sms it keeps stalling. But I also tried to use the same ALT.SMS.SmppClient with NowSMS demo and it worked just fine with bulk messages. Has anybody succeeded with sending bulk sms through smppbox/kannel? If yes, could you please tell me what smpp client you are using? Or perhaps there is something wrong with my configuration files.

What SMPP client is your ESME running? Also Kannel? == Rene From: Davit Mirzoyan [mailto:[email protected]] Sent: Tuesday, 17 August, 2010 19:04 To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client I am using gateway (svn) revision 4837 and smppbox (svn) revision 31. I tried also smppbox revision 33. Still the same. I haven't though tried another kannel version. Do you think it can be from the kannel version? Davit From: [email protected] To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client Date: Tue, 17 Aug 2010 17:19:06 +0200 Just a long shot: By chance, did you compile with another Kannel version that you are executing? What kind of (svn) version of smppbox are you using? And which Kannel version? == Rene From: Davit Mirzoyan [mailto:[email protected]] Sent: Tuesday, 17 August, 2010 17:10 To: [email protected]; [email protected] Subject: RE: smppbox bulk sms: slow reception from a client Hi, I kept playing around with the configuration files but still no luck. Today I tried to send 20 sms to smppbox but my smppbox or kannel kept stalling again. My system receives some 6 sms from my client and than it stalls for 1 minute or so before it continues receiving the rest. Moreover, my client does not receive all the deliveries back. It gets some 12 out of 20. I checked my log files and I noticed several error and warning messages. In my smppbox.log I get the following error and warning messages periodically.
