I have a multithreaded server - one thread / client.  I have a client
1 connected to thread A, and a I have client 2 connected to thread B.
After certain equal period of inactivity Client 1 sends a message to
Thread A.  Thread A receives the message, and sends it back to client
1 as well as client 2.  Client 1 receives the message succesfully but
then when Thread A tries to send to client 2 out of a sudden Thread B
throws "Connection Reset By Peer" where it was blocking on
.readObject(); (note that Thread B has not read anything from CLient 2
cause Client2 never wrote anything.) and then (right after that)
Thread A throws a "Broken Pipe" exception where it did .writeObject()
which is strange as Client 1 actualy receives the message succesfully
from thread A.  This only happens if there is a period of inactivity
on both clients, other than that everything works fine.

according to the error message "connection reset by peer" i guess you use a
tcp connection.
as tcp usually has a connection timeout sockets are closed after a period of
time without any traffic.
you may either send some dummy packets between your clients, or you  can
dynamically open and close sockets.
another idea would be to increase (or disable) connection timeout - but i
only know it _is_ possible, but not exactly _how_

hth (even if i'm late with that),
