Updated by Note: I think that the problem is probably somewhere else (memory corruption), the 'psi: tables count inconsistency' just catches this memory corruption. This problem is very difficult to debug so I cannot give any instruction which debug data might be useful.
It might probably help to run tvh inside debugger (gdb), wait for the crash and inspect the variables.
Another way is to disable some subsystems (EPG grabbers, reduce configuration etc) to try find the part of code triggering this corruption.

Note that I fixed a possible memory access/corruption issue in v3.9-1508-ga766245 . Could you re-test with the current tvh sources ?

Updated by You can close this bug ticket now. I have been running 3.9.1511 and had 3-4 recordings going on, doing a lot of channel switching and no crash yet.
Currently on 3.9.1526 and it looks good. :-)
