[asterisk-bugs] [JIRA] (ASTERISK-15845) CPU usage increases if WaitEvent not called

[Matt Jordan (JIRA)]

Matt Jordan closed ASTERISK-15845.
----------------------------------

    Resolution: Cannot Reproduce

I took the latest from Asterisk 11 and did the following:

* Pointed a browser at {{http://localhost:8088/manager}}, and logged in
* Kept the connection up by pinging the server every now and again (running "List commands")
* Constantly originated a Local channel that dialled a SIP channel to build events
* Verified that there were a pile of events in the eventq
* Watched top

At no point did the CPU climb noticeably.

As Leif pointed out, even if this was an issue, not calling WaitEvent periodically is a violation of the contract that the HTTP Manager has with its clients.

> If someone logs in via the mxml interface with reporting rights then all  events are buffered until they log out (or timeout) or call WaitEvent. If the timeout is long and/or they issue other commands regularly such as Status - but crucially not WaitEvent - then Asterisk starts to consume RAM and significant CPU. The RAM usage is obvious but I don't see why having 10,000 events waiting in the queue should cause increased CPU, although giving the command 
> manager show eventq
> in this case did cause asterisk to drop all current calls. Timeouts while list is locked I assume.
> ****** ADDITIONAL INFORMATION ******
> I have added something to the documentation in voip-info.org so users are warned about this gotcha.
