Does this happen any time you record two programmes parallel,
or was this the first time this has happened?

Apparently the video data stream of the first recording ended at 19:02:26.
Could it be that that channel stopped transmitting at that time?
I assume it was the KIKA channel, which ends at around 19:00.
If your timer tries to record past that time, VDR "sees" no more video data
and assumes the driver has crashed, so it initiates an "emergency exit" to
ultimately cause a driver reload and program restart. Maybe if the driver
becomes more stable one time we can drop these emergency exits again...

Please try parallel recording again at a different time, on channels that
broadcast for the entire duration of your timer.
