22.3.3 Queue Overflow Program Trace Error Message
A trace overrun error occurs when a trace message cannot be queued due to the queue being
full, provided program trace is enabled.
The overrun error causes the message queue to be flushed, and an error message to be
queued. The error code within the error message indicates that either a
program/data/ownership trace overrun error has occurred or that only a program trace
overrun has occurred. The next BTM will be a synchronization message. Refer to
Table 22-20.
The error message has the following format:
