We also received an avalanche of aberrant problems since our upgrade
ranging from disconnects to intermittent loss of connection (ie, user is
logged in, can ping one minute, not the next). We've even had one user,
who despite having a static IP, gets refused by sites running TCP wrappers
that report his IP address as the IP of the portmaster. We're thinking of
backleveling, atleast as a precautionary step, but I need OSPF at the
moment.
Do you have any tricks or tips you could share as far as disconnects? I've
gone through the whole 9 yards:
1. Verifying Inits,
2. Verifying Firmware (although the ISPorte has a new rev I'm going to
try)
3. Recabling (just replaced all my hand terminated UTP wire with Belkin
Cat5 10' cables)
4. Memory upgrades: livingston insisted my disconnect problem was due to
running only 1 meg of ram despite my large free heap never dipping
below 80k. I now have 4 megs in each, with sligtly more than 3 meg
free.
I've written a perl script to watch the disconnect causes on each port,
reporting the number of logins per port, the average call length, the
number of "Lost-Carrier" disconnects. Seems the average is a
"Lost-Carrier" in one out of every five terminations across the board.
What really scares me is when I see a user dial in for about 2 minutes,
disconnect with Input/Output-Octets being under 1k (in many cases about
20), a cause "User-Request", then dialing back in, sometimes
repeating about 3 or 4 times.
We're going to try to bring bell atlantic in to check our lines.
I'm going nuts here, Matt :-)
