Subject: Strange asyn errors

Hello,

I have an embedded IOC (ts7370) that runs an asyn driver.
That ioc is renning a seq sequence for data acquisition.
The acquisition should go as fast as possible.

I try to optimize the processing speed.
but from the asyn driver I get the following errors occasionally.
What do they mean?
How to fix them ?
