Hello,
I don't know what is rx_ignoreAckedPacket. I have thousands (up to 50000)
per 15 seconds of rx_ignoreAckedPacket on the fileserver. Number of
calls are less
(up to 10000). Is posible tenth calls of rx_ignoreAckedPacket?

We have this infrastructure:
Fileservers (large mode): OpenAFS 1.3.81 built  2005-05-14 (debian/stable)

windows and linux clients from version 1.2 to 1.4 and for experimantal use 1.5
OpenAFS 1.2.10 built  2005-04-06
OpenAFS 1.3.82 built  2005-08-20
OpenAFS 1.4.2fc4 built  2006-10-02
OpenAFS1.4.0101

Some of fileserver sometimes going to meltdown state (calls waiting
for a thread)
and don't know reason. There is 'rxdebug -rxstats':

Free packets: 935, packet reclaims: 1283, calls: 2197185, used FDs: 64
not waiting for packets.

Thanks for any answer.
