Yes.
There's been a series of bugs fixed in nsopenssl 3 and AOLserver 4 that have not been backported to older nsopenssl 2.1a and AOLserver 3 -- you could be getting bitten by one of those. However, those were all server-crashing bugs so if your nsd isn't crashing/restarting, then perhaps <jedi>these are not the bugs you are looking for ... move along</jedi>.
<jedi>I felt a disturbance in the force when I originally used AOLs 4 and nsopenssl 3 </jedi> so for the launch I switched to 3.3oacs1 and nsopenssl 2.1a. Its been rock solid up until now and your questions suggest that you have something in mind. Do you think these errors relate to a performance issue somewhere? Do you think a change of config would help - I'm running with maxthreads 20, minthreads 20, maxconnections 100 and maxkeepalive 0?
mii-tool gives an error - I'll check that out tomorrow. ifconfig was my first port of call and its showing 0 errors, 0 dropped, 0 overruns etc. No problem there that I can see.> > Is your upstream bandwidth > > provider having routing issues?

Check the output of "mii-tool" and see if it's actually negotiated a gig-e connection and if it's full/half duplex, etc. Check output of ifconfig and see if you're seeing any packet loss/etc. Basically, if any of the error counters are non-zero, you have some investigation to do ...
(Maybe someone stepped on your ethernet cable in the co-lo recently.)
Only if they climbed in the rack :-)
