FastIron SX 1600 - dm pp-dev 0 fa-stat questions

Yesterday one of our SX-1600 dropped all clients and phones on all its line cards.

I ran a :

dm pp-dev 0 fa-stat

and noticed that it was incrementing CRX drops, Total drops and CRC's where climbing like mad.

I failed over to the standby management card and that cleared the issues, however I don't know what CRX drops are.

I just know that it wasnt normal to see them.

Can anyone tell me what they are?  Or even better, tell me what anything in the output of this command shows me?

Thanks,

Davidt
