We've had a server for some time doing the same job with wowza 2.2.4 and have had a problem only now with slow to start videos.
by slow I mean 10 or 30 seconds, sometimes more.
The monitoring console shows nothing unusual, memory doesn't exceed 90Mb (usually 40-50). Classes are stable at around 3300. cpu rarely moves above 1%.
The thread count though starts at 70 when I reboot the service and can end up at 400 fast. It will stay there quite consistently and will fall very briefly to 350 from time to time.
These are my working parameters since I've added _definst_ to my stream URLs.
I can watch 5-6 videos fine and the problem will occur/start again and not stop until I reboot the service.
This is totally new and there is nothing in the apache/symfony/wowza logs since instance correction was done.
If someone has ANY idea why, please, this is getting critical.
