ADuM1250ARZ stops communication on slave side

Hello everybody,

 

I use an ADuM1250 opto Isolator to connect a microcontroller with die I2C outside bus.

For a short time (some minutes) the communicaton works fine, until some occurences on slave side stops the communication on the slave side. On master side I can see, that no slave is reachable.When I Switch off/on the powersupply on slave side the communication continues working.

What happens there? I'm desperated.How can I make it more solid?

 

Thankyou in advance for every tip!
