Maximum UOW limit of 100 Reached - This message indicates that more than 100 source UOW's have not been acknowledged by the engine back to the source capture/publisher. This message may simply be a symptom of a slowdown in the Kafka cluster or that the Kafka configuration in use by the engine is either not being properly referenced or contains one or more errors. First thing to check is the location of the sqdata_kafka_producer.conf file. The "working directory" specified in the sqdagents.cfg file may conflict with the files actual location and the Engine's requirement for it to be in the "working directory" at run time.
