Hi all,
I'm using the OpenSER in a scenario in which I distribute incoming SIP calls among three gateways. Basically all I do is
route[4] { if (uri=~"sip:.+[0-4]@") { t_on_failure("20"); route(20); } else if (uri=~"sip:.+[5-7]@") { t_on_failure("21"); route(21); } else { t_on_failure("22"); route(22); } } route[20] { #### route[21] and [22] similiar rewritehost("111.222.333.444"); if (!t_relay()) { sl_reply_error(); }; } failure_route[20] { if (t_check_status("503")) { log(1,"Overload detected on XXX - try YYY\n"); t_on_failure("3"); append_branch(); route(21); } }
I see several error messages every second and they all look like this:
BUG:tm:run_failure_handlers: stack level is 1!!
Can anyone explain me what is causing this?
Regards, Stefan
