Description
We have a fairly large-ish instance of MaxScale. At March 10, we had the following counts after running the instance for 16 hours forwarding all SQL traffic from a very large message board to three MariaDB MySQL nodes:
MaxScale> show services
|
[...]
|
Number of queries forwarded: 152065870
|
Number of queries forwarded to master: 7151735 (4.70%)
|
Number of queries forwarded to slave: 144914137 (95.30%)
|
Number of queries forwarded to all: 25297037 (16.64%)
|

Looking at the counters today, the values are negative:
MaxScale> show services

|
Router: readwritesplit (0x7f34aa8232c0)

The value of "queries forwarded to slave" is changing and goes towards zero. it seems some sort of an integer overflow happened. Is it possible to get it fixed?
