Why do i see the following error messages in my 'Query Error Logs' and what do they mean?

ANSWER |
These errors appear in Query Erorr Logs in the event where you added two MySQL DBs with different versions with in a cluster one after the other. For instance, if you initially had a MySQL 5.6.13 which has a version length of 6 bytes and then later added a MySQL 5.7.136 to the same cluster which has a version length of 7 bytes.
ScaleArc uses a static variable to store this length at the startup when the very first client connection to ScaleArc is established (servergt).
Now with the second dbserver in the cluster with new version length, though ScaleArc will modify the greeting with the newly generated value correctly, it will yet log the discrepancy in the error log.
That said, you may safely ignore these errors as they have no impact on any functionality. You may also opt to restart ScaleArc clusters once to suppress these errors.
These are also charted out and tracked for getting dynamically handled without logging in the future ScaleArc release.
