 In cases where the message payload is greater than 32 KB or is in binary format, run the CheckMalformedEvents.cs code available in the [GitHub samples repository](https://github.com/Azure/azure-stream-analytics/tree/master/Samples/CheckMalformedEventsEH). This code reads the partition ID, offset, and prints the data that's located in that offset. 
 
+Other common reasons that result in input deserialization errors are:
+1. Integer column having a value greater than 9223372036854775807.
+2. Strings instead of array of objects or line separated objects. Valid example : *[{'a':1}]*. Invalid example : *"'a' :1"*. 
+3. Using Event Hub capture blob in Avro format as input in your job.
+4. Having two columns in a single input event that differ only in case. Example: *column1* and *COLUMN1*.

 ## Job exceeds maximum Event Hub receivers
 
 A best practice for using Event Hubs is to use multiple consumer groups for job scalability. The number of readers in the Stream Analytics job for a specific input affects the number of readers in a single consumer group. The precise number of receivers is based on internal implementation details for the scale-out topology logic and is not exposed externally. The number of readers can change when a job is started or during job upgrades.
