Issue with live streams getting long delay

We run 15 live 24/7 streams on Wowza using 2 origin servers and 2 edge servers. The origin servers are transcoding to multiple bitrates and creating an HLS stream.

Recently we have found that streams are getting an increasing lag over time. The most we’ve seen is 15 minutes before we’ve restarted all the Wowza services which has restored the delay to an acceptable couple of seconds.

This is happening multiple times per week and we’re not able to see any obvious issues. CPU, Graphics card, RAM are all in the 20% level and the hard drives aren’t being used. The servers are all dedicated to this task and have dedicated graphics cards.

How can I gather details to work on this issue? Where do I look?
