Length (0) is 0 or query string allocation failed ((nil)). Buffer is 5 bytes.

Hello Team,

Our maxscale log is getting over-flooded with the below error,

Error:
------
2017-09-14 04:43:22 error : Length (0) is 0 or query string allocation failed ((nil)). Buffer is 5 bytes.
2017-09-14 04:43:22 error : Unable to parse query, out of resources?

We are using version : maxscale-1.4.5-1.x86_64

We are using maxscale for RW splitting with master-master replication with one being active and other being Passive(Reads)

While checking Maxscale we could see queries being routed to respective node, kindly provide solution to fix the same

Thanks
