[rescue] tcpdump and nfs questions

[Joshua D Boyd]

23:55:53.972842 servitude > 192.168.0.4: icmp: ip reassembly time exceeded 
(DF) [tos 0xc0]

So, what does this mean, and could this be related to my NFS problems.  
Servitude is the NFS server, 192.168.0.4 is the workstation, and something 
happens such that anything that tries to use a file or folder on the nfs 
partition freezes for long periods (5 mins to an hour), then everything 
seems to write itself, and most of the frozen tasks pick up from where 
they froze.

I just noticed that I've been getting quite a few of these errors in the 
past 30 minutes, a time frame that this NFS "freeze" has been in effect.  
I don't remeber seeing them other times, but I could be wrong.  I don't 
seem to get any error messages on either machine (client or server) during 
the NFS frozen times.

These messages seem to be a bit more connected.  There doesn't seem to be 
any pattern between when the previous error shows up, and when these 
do.

Also, this seems to be totally unrelated, but what does this:
00:04:08.461830 192.168.0.1.bootpc > 255.255.255.255.bootps:  
xid:0x49435320 secs:10752 flags:0x8000 [|bootp]
mean, and why am I getting it?

192.168.0.1 is a windows 98 machine running MS Internet Sharing (still 
haven't gotten my IPX to take over as firewall).  Thing is, it shouldn't 
be trying to boot, and also there is a switch (3com lanplex 2500) between 
the machine I'm  sitting at and that one.  The machine I'm sitting at has 
an IP of 192.168.0.4.

Sorry to keep bugging you guys about this, but my NFS problems are wierd, 
and I'm in way over my head with them.
