THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Jack Wang (GoGoJack) Attached to Project - sip-router Summary - Kamailio doesn't to handle any SIP message at all after several dialogs... (CPU high usage) Task Type - Bug Report Category - Core Status - Unconfirmed Assigned To - Operating System - Linux Severity - Critical Priority - Normal Reported Version - 4.0 Due in Version - Undecided Due Date - Undecided Details - First, thanks for watching my poor English, hope guys can understand what I want to show you :) __issue __ * Objective: test the stability of kamailio with lots of registered users * Work: take 4~9 users registered and do call in\out with an MCU I found it's OK for just doing registration actions , but a trouble always occured when doing call in\out for a time (5 minutes ~ 3hrs , frequently in 1~2hrs) - kamailio doesn't to handle SIP message anymore, this causes that all the registration failed and was changed to "expired" state in user location table of database so that I can't do call in\out for every register user until I restart kamailio. It seems CPU usage of kamailio is too high after checking by typing "top" command: **[normal state]** <code> CPU: 0.2% usr 0.2% sys 0.0% nic 99.5% idle 0.0% io 0.0% irq 0.0% sirq ...
