Bryce, Des: Noticed what seems to be a bug: If DelayAfterSend=[msec] is used for a modem uplink and values are set from 1000 to 4000 - the modem's throttling outbound messages at proper intervals. But if the value is set to 5000 the delay would fluctuate between 18 and 23 seconds. We've tried and confirmed it with two modems separately on the same server with moderate load on SMPP uplinks and low load on modems. 1000, 2000, 4000 and 5000 ms. were tested, but no values larger than 5000. The service was stopped-started after each configuration change. NowSMS version is 2009.12.08. While it's a minor annoyance for us I thought it may cause trouble to other customers, so you may want to patch it. Kind regards, Ashot | |||

Hi Ashot, I haven't been able to recreate this. I've tried delays of 5000 and 6000, and both worked properly, giving a 5 and 6 second delay, respectively. I asked our engineers to look for problems in this area, but they haven't come up with anything. I'd be curious to see an SMSDEBUG.LOG to see if it shows some other sort of error occurring. -bn | |||

NowSMS version is 2009.12.08. Also note that these modems are also receiving messages, at an average rate of perhaps 5-10 per minute. No heavy receiving was noticed during the second send attempt. Modem receive mode is set to Direct Phase 2+. Funny indeed. Kind regards, Ashot | |||

Hi Ashot, This is very strange. It is the modem that is triggering the extra 15 second delay. NowSMS starts the send process after 5 seconds, as it should ... but the modem takes 15 seconds to send the message ... instead of the normal 2 to 3 seconds. I don't know why this would happen. I don't know if it is some sort of operator specific or modem specific situation. In our tests here, we haven't seen any behaviour like this. -- Des NowSMS Support | |||

Hi Des, You are right: it does look like the modem's delaying the responses, but why only if the throttling's set to 5 sec. remains a mystery. We can consistently recreate the scenario on all 16 modems.. Too bad I can't make PortMon work on this server for some reason. I'd have checked the serial exchange for spurious commands.. We're fine with 4 sec. delays, let's consider it network-specific. Kind regards, Ashot | |||
