IPX dropouts on -stable

[Antony Mawer]

Hi all,

We've had issues with some internal servers that we're running that use 
IPX + mount_nwfs to connect to a Netware 4.11 server. On some networks 
it works fine, but on many of the others the connection drops out after 
a few minutes and the mount point becomes inaccessible.

The odd part about it is that if I killall IPXrouted, then re-start 
IPXrouted, the connection will spring to life again.

The machines are running on FreeBSD 4.7 at this point, but looking at 
CVSweb, there doesn't appear to have been any significant changes 
applied to 4.x since then, and all the work on 5.x appears to be locking 
related.

Has anyone experienced this problem on older or recent -stable? Any 
suggestions or pointers? Thanks!

Regards
Antony
