Leap second & FS using more CPU
I was wondering why FS which usually uses only 8-10% CPU at for my 20 active calls was suddenly using 60%. I was pointed to the leap-second being a possible cause. So, as per: http://marc.info/?l=linux-kernel&m=134113577921904 I ran: $ date -s "`date`" and the CPU usage went immediately back to the norm. Not sure if it glitched the audio when doing so, though... This is just a PSA and YMMV. -Avi
Thanks for the notice. I ended up doing a rolling restart of all my servers because of that, so did not end up losing calls but took forever. Brian Foster Endigo Computer LLC Sent from a mobile device. On Jul 1, 2012 5:16 PM, "Avi Marcus" <avi@avimarcus.net> wrote:

Avi, thanks for the info. There is also a Jira for this, so I guess we can close that one again, or maybe let it stay open for a couple of days, so it's easier for people to find. http://jira.freeswitch.org/browse/FS-4372 About glitches in audio - since FS uses a monotonic timer it shouldn't be a problem. /Peter 1 jul 2012 kl. 23:23 skrev "Avi Marcus" <avi@avimarcus.net<mailto:avi@avimarcus.net>>: I was wondering why FS which usually uses only 8-10% CPU at for my 20 active calls was suddenly using 60%.
