Hi Jueri,
> callbackRequest: cbLow ring buffer full
You're overrunning the ring buffer for low priority callbacks. Try
bumping up the size by running
callbackSetQueueSize(x)
x depends on the number of outstanding callbacks you can have. For our
IOCs a good rule of thumb is to set it to at least the number of records
communicating with the hardware.
On modern versions of EPICS you can monitor usage of the callback queues
by running the following command on the IOC shell:
callbackQueueShow
Similar commands are available for the scan once queues:
scanOnceSetQueueSize(x)
scanOnceQueueShow
We saw bad things happen as a consequence of callback-queue overruns so
I would recommend to fix the queue overruns first and see if you can
reproduce the assert.
