[Tilecache] Connection reset by peer error

I am still trying to resolve this problem...
I have noticed that the problem occurs ('connection reset by peer'
exception') also when tile is already cached by tilecache, so I think that
it is not the problem with WMS server...(when tile is cached tilecache does
not connect WMS server).
So, my conclusion is that it is rather problem with connection between IE
and tilecache. I am using tilecache by launching 'tilecache_http_server.py'
script. Exceptions like 'connection reset by peer' occur from time to time
and, after a week or two tilecache stops responding at all and needs to be
restarted. Below is the log... Any sugestions ? I am loosing my mind... :(
PS: adresses such as 10.97.88.39 are adresses of clients requesting tiles
from tilecache..
