Tvheadend

I'm running Tvheadend for quite a while now and really like the software.

For descrambling i have both Cccam and Oscam connected to Tvheadend, i use oscam next to cccam because cccam wont support multiple tuners.

Now when changing channel, and because cccam/capmt fails to obtain key because it is already active on another adapter, the key will be fetched trough oscam (proxy). This works perfectly, but in this situation capmt keeps trying to obtain a key even when already cwc found the key.

Is there are way to make Tvheadend stop requesting a key via protocol A if there has been a key found using another protocol? So in my case, When the key has found by CWC, Capmt can stop trying to get the key.. currently it continues to look for the key which in the end crashes Tvheadend!
