h0epics2 ground to a halt yesterday with 0% cpu idle time. I restarted it and as of now it is still nicely at 98% idle.
The FMCS PC was reconfigured yesterday presumably by the vendor, its network firewall was strengthened which prevented the FMCS EPICS IOC (h0epics2) from accessing the PCs web pages.
I reconfigured the WIN7 inbound rules to allow access to the HTTP port on the FMCS PC and restored the EPICS connection.
