Tvheadend

Hi,
I usually suspend my QNAP NAS when I am not using it. Since I installed Tvheadend, the suspension has failed. The NAS remains in a strange state, it is no longer operational, but it is not suspended. HDD LEDs 1 and 2 continue to flash, LEDs 3 and 4 are steady on.
All HDDs stop spinning. NAS becomes inaccessible and only by holding down the power button can you turn it off completely. When I turn it back on, the file system is dirty and the operating system warns me that it needs to be cleaned.
If I uninstall Tvheadend everything goes back to normal. NAS suspends regularly with all HDD LEDs off, only the network activity LED remains flashing.
Can anyone give me some advice?

Tvheadend version is: HTS Tvheadend 4.3-1804 ~ gebb096804
QNAP Operative System is: 4.4.2.1270
Intel (R) Celeron (R) CPU N3160 @ 1.60GHz 8Gb Ram

Thanks in advance.
