In my case, I can almost set my watch to it (if I had a watch) ... every 3 
days, 2 hours, it seems that I have to reboot this machine, as that is when the 
'No Buffer Space Available' r starts to be generated ...

There are two others (CC'd in this) that have experienced the same ...

Chris / Thiago ... in your cases, are you finding that it happens as regularly 
with your servers?  Thiago, I believe you ended up reverting to an older kernel 
to clear up the situation?

I've included my 'netstat -m' report ... from it, it doesn't look to me like 
its an mbuf issue, or am I missing something?  Is there something else that, in 
74 hours, I can provide before I do the reboot?

Chris, you mentioned reducing recvspace/sendspace to correct the issue?  Has 
that fixed it for you, or just prolonged until it happens again?  How did you 
set this?  I've checked both the man pages for ifconfig and fxp, and don't see 
anything ... ah, just found it doing a 'sysctl -a' ... can you post your 
settings from /etc/sysctl.conf?  or did you set it somewhere else?  I'd like to 
try that and see if maybe that changes my '74 hours uptime', either good or bad 
...
