Hello, we are currently seeing some strange behavior under load conditions. Notifications for calls are sent to seemingly random subsets of subscribed users. This already happens with the default configuration. To recreate this we have created 10000 SUBSCRIBEs with sipp for 1002. sipp -sf sip.xml $ip_of_freeswitch -m 10000 -r 100 Meanwhile sngrep is running to record the dialogues, and we have 2 telephones registered to 1001 and 1002. When 1002 calls 1001, NOTIFYs will be sent out to the subscriptions. However when there are 10000 subscriptions only about 3000-4000 of them will get the NOTIFY. Trying it again will cause another subset of the SUBSCRIBEs to be answered with a NOTIFY. This test was conducted locally on an otherwise idle server, so network loss can be ruled out rather well. Has anybody else had a similar experience? I couldn't find any way sending out NOTIFYs could be limited and the number of NOTIFYs we get seems to be to random for such a limit.
