Overruns and Underruns on Cisco Aironet 340 wireless bridge

[lbrannon4]

What would cause overruns and underruns on Aironet Wireless Bridge (340). Is it a hardware issue? The other line of sight bridge is fine. Thanks.

Overruns: Number of times the hardware receives First-In-First-Out (FIFO) overflow,This should be a rare occurrence.

Underruns: Number of times the hardware transmit FIFO became empty during a transmit. This is a rare occurrence.

This can be hardware problem sometimes
