Folks,
We found a problem with CAJ and the PV gateway yesterday. The problem is that CAJ "out of the box" (e.g. without changing any of the default properties) will connect fine to PVs on the local subnet if they are contained in a VME IOC or soft IOC. But CAJ will not connect to PVs that are present in a PV gateway on the local subnet.
We've figured out the problem, and it is easy to reproduce even with traditional CA from EPICS base. The problem is that CAJ defaults to a broadcast address of 255.255.255.255 when searching for PVs. VME IOCs and soft IOCs respond to such a broadcast, but the PV gateway does not.
