Hi, I was testing the new dynamic pipelimit instantiation functionality heralded in 4.2, and, strangely enough, it doesn't seem to work at all. Every time I call pl_check(), it just blocks the worker thread indefinitely, until I--rather quickly--run out of available workers. I've tried it with db_url (which I gathered to not be mandatory), without a db_url, using every algorithm possible, with a static pipe name, with a PV pipe name, etc. It all yields the same results. Here is my current employment of it: if($(xavp(call=>ingress_cps_limit){s.int}) > 0) { xlog("L_INFO", "DEBUG: PRE PL CHECK $ci\n"); if(!pl_check("1", "RED", "2")) { xlog("L_INFO", "DEBUG: AFTER PL CHECK $ci\n"); pl_drop(); xlog("L_INFO", "Ingress call setup rate limit for this BG " "$(xavp(call=>ingress_cps_limit){s.int}) has " "been exceeded; rejecting call\n"); exit; } xlog("L_INFO", "DEBUG: AFTER PL CHECK $ci\n"); } modparam("pipelimit", "hash_size", 12) modparam("pipelimit", "timer_interval", 5) modparam("pipelimit", "reply_code", 503) modparam("pipelimit", "reply_reason", "Call Setup Rate Exceeded") I never reach "AFTER PL CHECK". Here's what I actually want to do: if($(xavp(call=>ingress_cps_limit){s.int}) > 0) { if(!pl_check("$avp(trunk_id)", "RED", "$(xavp(call=>ingress_cps_limit){s.int})")) { pl_drop(); xlog("L_INFO", "!> " "Ingress call setup rate limit for this BG " "$(xavp(call=>ingress_cps_limit){s.int}) has " "been exceeded; rejecting call\n"); exit; } } I tried upping debug to debug=3 but get nothing insightful that pertains to pipelimit at all, as far as I can see. This is on a stock CentOS 6.5 install, sip-router:master:36e695453762b5ed15e5048fad2c559bb239dad5 compiled from source.
