Description Frank Hirtz 2001-11-09 16:27:23 EST
Description of Problem:

we've seen 2 strange problems:

1) netstat displays 2 identical lines

netstat -a |grep piics2
tcp        0      0 hqias4:mtflocal         piics2:33135
tcp        0      0 hqias4:mtflocal         piics2:33135

2) netstat display this:

 warning, got bogus tcp line.
tcp        0      0 hqias4:mtflocal         piics2:33235
ESTABLISHED ufilter    7312379
warning, got bogus tcp line.

Preston evaluated this and indicated that it could affect the performance
of anything using the proc/net/tcp, but it was possible to change netstat
to filter for duplicate entries.

Could you be a little more specific in how to recreate this problem? Otherwise
it's kinda hard to check if a fix actually fixes the problem.


Read ya, Phil

I still cannot reproduce this bug. Closing as works for me now.

I am getting this error but not on a consistent basis. One more thing 
which might help replicating the issue is that we have too many 
connections in the CLOSING state.
