The problem looks like that the zeromq mode does not call the (void outputBufferBegin(uint32_t dictId)) function in src/OutputBuffer.h. In my opinion, I can only find this place.

[LoveChina-3000]

I change the OpenLogReplicator.json ,"type": "protobuf" to "type": "json".Now I can run for a while

[bersler]

Right, there is a bug in protobuf code, I am now testing the fix. I will include a fix in next code push to github. Thank you for reporting, @yetengfei .
