Hi Sebastian, This is very good information, thank you for reporting.
1) Do you think this phenomenon corresponds to pushing messages into Kamailio and actuating the event_route to process them? Or might it be triggered by activity in the other direction, e.g. sending EVAPI messages out of Kamailio? 2) Does the problem recede if the throughput drops below 500 RPM? -- Alex > On Jan 30, 2023, at 5:40 PM, Sebastian Sastre <sebastian.sas...@getweave.com> > wrote: > > Hello > > We are currently using EVAPI to push messages into kamailio from a go app. > For the most part ift works without problems, messages get delivered into the > event route and we use it to update presence status. > > Recently we started noticing delays on the evapi processing.
