Description

This bug has been noticed for several weeks now. However now have the proper debugging environment to catch logs and stacktrace about it.

Symptoms:

1* Start tvheadend - works very well to begin with
2* Left it network scanning (sat>ip, inverto IDL-400s)
3* After about 12 hours - tvheadend process is now using >75% CPU on 1 core
4* Tvheadend still works (but considerably more slowly)
5* After about 24 hours - tvheadend process is now using most CPU of BOTH cores.
6* Tvheadend crashes / runs out of resources.

Today I have taken live stacktrace at point 3* - after about 12 hours. Files attached.

If you require more logging, then please specify the extra sub-systems you need, then I can re-run the test again. Many thanks.
