auth2 coredumps

I have been observing the following behaviour. On the client side,

(root) some-client /root > au nu          
Your Vice name: codaroot
Your password: 
RPC2_Bind() --> RPC2_SUCCESS
Vice user: cgu
New password: k
New info: k
AuthNewUser() --> RPC2_DEAD (F)

On the server side, the auth2 daemons core dumps as a result of "au nu".
The /vice/auth2/AuthLog file reads:

Date: Wed 10/20/99

18:16:43 Reallocing from 100 to 1000
18:16:43 Server successfully started

18:16:54 In PWGetKeys()
18:16:54        vid = 500
18:16:54        vid = 500
18:16:54 AuthNewConn(0x1a9212ab, 0, 66, 2, 500)
18:17:06 In PWGetKeys()
18:17:06        vid = 500
18:17:06        vid = 500
18:17:06 AuthNewConn(0x3a8c9303, 0, 66, 2, 500)
/vice/db/auth2.lock: Bad file descriptor

Previous to the "au nu" call, I could an acquire tokens without
problems, that is clog succeeds.

A stack trace of auth2 gives,

The SCM is running RedHat 6.1, with Linux kernel 2.2.12-20. I seached
the mailing list to check if this was a known issue. Apparently
not. Regards, Ceki
