This looks like socket glitches. Somehow the socket gets disconnected in one side without notifying the other.

My advice would be to:

1. Check if you are using the connection porperty 'tcpKeepAlive=false'.

2. Try different values for connection property 'socketTimeout'.

3. Analyze sockets state when this occurs (both in client and server).

4. Try to tweak c3p0 connection validation timeout.
