[c-nsp] HEADS UP: vlan_mgr crashing in NX-OS 5.2(3)

[Bernhard Schmidt]

Hey,

just a quick heads up, maybe someone is hitting that, too. Since
upgrading our test Nexus 7000 from 5.2(1) to 5.2(3) this morning we have
a failover due to a crashing vlan_mgr process every hour. It turns out
"sh vlan" (which is executed by RANCID every hour) reliably kills the
box.
