Severity: 3-Major


In rarely occurring cases, HSB RQM queues configuration becomes corrupted, which leads to HSB receive failures. In some cases, all queues above 64 are all disabled, although the lower queues are configured and enabled with no packet drop. In some other cases, all queues are disabled.


The receive failure leads to HSB lockup, and will impact traffic.


-- Using 5000s/5200v, 5050s/5250v/5250v-F platforms. -- Specific conditions under which this occurs have not been reproduced.


Reboot to recover, or disable ePVA to avoid lockup at the cost of some performance degradation.
