Memory Buffers (U/F/A)
Displays the number of memory buffers currently used, free, and allocated.
Communication Errors
Displays the current count of communication errors between the RS4 and RZ2. This
value should be zero. If not, the current data session may contain gaps in the data, which
will be written to the log
fi
le.
If the count increases continuously at a high rate (>1500 errors per second), the RZ
connected to that port might not be synchronized to the PCI card. Check the
fi
ber optic
connection from the RZ device to the PCI card and use zBusMon to con
fi
rm RZ to PC
communication, and reboot both the RS4 and the RZ2.
