We've seen this problem in 2 of our busiest POPs. One has a 5 box stack,
the other has 6. 2 PRI's per box. except on the last box in the 1st POP,
which has 3. All boxes running 5.0Ap42. RIP2 send/receive. All users are
ISDN, mostly 128k dialup. the 5 box stack runs at 80-90% utilization all
the time, the 6 box stack a little lower, maybe 60%.
When this happens, it's only 1 box that goes flaky. when i connect w/ 1
channel everything's fine, pings work. As soon as the 2nd channel is
broght up to that box, pings stop and the connection freezes. then after a
minute, the 2nd channel times out and drops. Then pings on the 1st channel
start up again. Resetting the affected box fixes it. This happens when
the 2 channels fall on different boxes and 1 of the channels falls on the
one flaky box. if the channels fall on 2 other boxes, or the same box.
The MP connection works normally.
This doesn't happen too often. About 3 times in the past 2 months. But,
we have high dollar users connecting to these boxes, (128k dedicated, etc)
and I'd prefer it not happen anymore. We've been running 5.0Ap42 since mid
january and before 2 months ago, the code has been working perfectly.
