Since no-one else has replied, I'll have a go. I've solved a similar
problem here by using a timer to make dummy queries of the db from the
clients every 5 minutes or so. My guess is that after our last network
upgrade, the new n/w equipment drops inactive connections after some
time (30 minutes?) to allow reuse of dynamically assigned IPs(?).
