[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=210316#comment-210316 ] 

Matt Jordan commented on ASTERISK-22541:
----------------------------------------

This is sort of like asking people to find a needle in a stack of needles while blindfolded. You'll need to provide a lot more information. Some obvious standard things that would help:
# What channel technologies were involved
# How were they bridged (native - local or remote - or core)
# Is recording being used in any fashion

Please attach the relevant portions of your dialplan, as well as channel driver configurations. Any log information during the loaded period would also be useful.

You could also use gdb to dump out a backtrace of the threads during the loaded periods. That would tell us what the system is actually doing during that period of time.

>    Affects Versions: 11.5.1

> Not sure exactly best way to reproduce, but upgraded Asterisk 11.4.0 to 11.5.1 and immediately saw a 10x spike in CPU usage, with no other changes to the system itself.
> System has around 800 peers and 30-50 concurrent bridged calls.  Under even moderate load, the 11.5.1 system spiked to 2 full cores, where before it was running about 20% of one core.
> Reverting the system caused everything to go back to normal.
