The trouble continues in Trimble Hall. A malfunction occurred with the same symptoms. We have isolated the problem to the switch in Trimble 007. We disconnected the TH network piece by piece while monitoring connectivity with ping. When the 007 switch was disconnected, connectivity returned. Upon reconnecting the 007 switch, the network maintained connectivity. We will have to wait until the next failure to isolate the trouble to a specific port on that switch.

redherring, the SNAP Appliance for OIS, was upgraded from version 3.0 to version 3.4.
Cascade Web Server Misconfigured
Becuase of a change to Cas9i, the Cascade web server, shasta served a blank home page. The script that created that page was pointed to the wrong database instance. The error was corrected.
New Best Access Server Installed/Configured
A new Dell PowerEdge 1650 server was installed to serve as host to the Best Access system, which will move off Ketron.

Database Servers dropping connections, losing packets
The database servers, tahoma & baker, and the frontend forms servers snidley, dudley, and fenwick, began dropping persistent client Oracle and telnet connections. ICMP packets were also lost.
Speed and duplex settings on the switch ports to which these servers were connected were checked and found to be correct (100 Mbps, full duplex).
The problem cleared up after about 1 hour. Will check further.
Best (Lenel) System Stopped Polling and Recording Events II
A corrupted dabase trigger in the basis Oracle instance caused the B.A.S.I.S. system to stop polling and recording events.
The faulty trigger was LENEL.EVENTS_SPEEDY_TI1, and the fault was the insertion of carriage returns within two AND operators.
Paul corrected and revalidated the trigger, which cleared the problem.
Best (Lenel) System Stopped Polling and Recording Events I
Ketron was rebooted to attempt to clear a “Polling Stopped” error with the B.A.S.I.S. software. It did not clear the problem.
