Is everything on a single host, or do you have ISS running on a
different machine?
If they are separated, some firewall software and hardware will kill
connections that have not been used for a certain amount of time (often
a few hours). If your AJP13 connection is dying overnight when nobody is
using it, perhaps you have a router or firewall configured to close
inactive connections.
