Update to 2009.05.08 at the same URL link ... http://www.nowsms.com/download/nowsms2009rc.zip. There was a restart problem that we found which involved a problem processing unresolvable delivery receipts. That may be the issue that you are facing. If that does not resolve your problem, as a temporary fix, please try downgrading to NowSMS 2008. -- Des NowSMS Support | |||

Hello! We also faced such problem in all NowSMS releases. If queue exceed of about 50 000 messages and you don't have fast enough outbound SMSC links - NowSMS starts rapidly reboots. I'm not sure that it caused unresolvabled delivery receipts. Some errors in software logic. Regards, Alex K | |||

That's the first I've heard of this issue. There is a configuration parameter that might provide a work-around. Under the [SMSGW] header of SMSGW.INI, add OldRoutingLogic=Yes. This will have a negative performance impact, but it disables some caching of message queue information ... and this cache is the only part of the software that would care how many messages are in the queue. -- Des NowSMS Support | |||

Hello again! I think we have found some issue, if you set up routing like that: [SMPP - XXX:YYY] RoutePrefOnly=Yes Route1=+???????* Route2=!+44????* AllowedUserOnly=Yes AllowedUser1=test_user1 AllowedUser2=test_user2 [SMPP - XXX:YYY#2] RoutePrefOnly=Yes Route1=+???????* Route2=+44????* AllowedUserOnly=Yes AllowedUser1=test_user1 AllowedUser2=test_user2 If users submit messages to UK (+44) and we have restrict access to UK on 1st connection (Route2=!+44????*) seems it has very strange influnce on performance, speed decreased X4 on 1st connection and after q reached 50k NowSMS starts reboots rapidly. Could you please check that issue? When we have changed routing - situation normalized. Regards, Alex K. | |||

Hi Alex, I'm seeing the performance issue, but I'm not seeing the restarts with a large queue. I'm trying different configurations to look for clues, but there must be something still that I am missing. -- Des NowSMS Support | |||

I take that back ... I did just have the problem occur ... now to find the pattern. | |||

Hello Could you confirm that issue connected with restricted route(Route2=!+44????*)? or it is general performance issue? Regards, Alex K. | |||

I need more details on this ... any error messages? I suggest you create a new thread with more details on the specific problem that you are experiencing. -- Des NowSMS Support | |||

After many hours, I finally do have some updated information on this. As expected, the OldRoutingLogic=Yes parameter did provide a work-around, but at a very severe performance penalty. The best way to recreate this problem is to connect to an SMPP server that has a very low enquire link timeout requirement. It is possible to trigger the problem in scenarios with higher timeouts, depending on computer speed, hard disk speed, and overall message queue size. But I had the best success replicating the problem by connecting to SMPP servers with low enquire link timeouts. The problem is not necessarily related to the "!" routes. But when there are more routing conditions defined, it does take longer to evaluate them. The problem occurs when there are a large number of messages queued, but one or more connections are ineligible to process any (or very few) of the messages. After establishing an SMPP connection, NowSMS begins scanning for messages that are eligible for routing via that connection. During that scan, no enquire link timeouts are sent. If the SMPP connection drops before either NowSMS finds a message to send or the scan is complete, a logic error triggers the restart. We're in the process of fixing the logic error that triggers the restart, and the error that prevents the enquire link from being sent. There are a few more tests to run, but I should be able to post an update within the next 24 hours, maybe 12 hours. The fix appears to have minimal impact on internal logic, so at this point we're not expecting it to introduce any new problems. -- Des NowSMS Support | |||

Update on this issue. I've gone ahead and updated the download at the following link with an update to address this issue: http://www.nowsms.com/download/nowsms2009rc.zip If the installer reports a date earlier than May 21, 2009 ... then you may need to clear the cache in your browser in order to get a fresh download. -- Des NowSMS Support | |||

Hello, Seems that issue is not fixed completely, if queue exceeds 100k, nowsms doesn't reboot but freezes for 3-5 rapidly. CPU load goes from 95-99% to 3% and we see that statistics doesn't updates for that period. We test 20090630 realize. Please advise where could be a problem. Regards, Alex K. | |||

Hi Alex, Hmm.... I think you might be facing a different issue. Edit SMSGW.INI, and under the [SMSGW] header, add CacheQSize=Yes This setting has no effect on the server itself .. . it affects the front end configuration interface. The configuration interface does a periodic scan of the message queue. When the queue is very large, this scan can cause problems ... the scan seems to eat up Windows resources which severely slows down file i/o from the server process. This setting disables the configuration interface from performing this scan. Instead, it reads information from the server process. I'm not sure why we haven't made this setting a default. -bn | |||
