Since todays pacman -Suy, the mythbackend process on my raspberrypi3 goes will, it is stuck at 100% CPU load, consumes approximately 75% of system memory and if a client connects, it is very very slow to respond and after a short while dumps core or is killed by the kernel because it is out of memory.
Before today, it has been running just fine for two years or so. I downgraded the package again, but this didn't make the process behave, also I empties the database and set mythtv up from scratch, this changed nothing.
There is nothing unusual in the system log, also running mythbackend with the --loglevel=debug flag did not give me any useful information. Therefore, my bug report is rather unspecific at this point. Can someone advise what I have to do to make it more useful?
