Hello,

I've got this message from slave IceGridRegistry. It was running happily for weeks, but then it suddenly stopped and its log file ended like this:

TcpTransceiver.cpp:420: Ice::SocketException:
socket exception: The semaphore timeout period has expired.

Apparently there was a temporary network outage preceding the crash. I am using latest Ice 3.4.2. Any ideas why it couldn't recover?

Kind Regards,
Marian
