After updating from 1.5P16 to 1.6P07 cee we got severe problems with the stability of the master slave communication. We have about 16 slaves, but the communication to 3 slaves on one hardware brakes in a random time interval.
The liveproxy log on the master shows a lot of following errors:
2020-01-16 10:46:26,162  [cmk.liveproxyd.(67016).Site(XXXXX).Client(72)] Cannot send error message to client: [Errno 9] Bad file descriptor
Anyone any idea where to start fixing it?
