Resolution

The values below are generally used for these parameters:

COMMANDMAX 4000
COMMANDRATE 100

MESSAGEMAX 10000

As a general rule, check he value of the parameter COMMANDHIGH and MESSAGEHIGH on the OPSVIEW panel 4.1.1. If you see they are reaching their respective maximum values then you need to increase them.
