Hi all members,

my name is John Kettler and i am a beginner.

I use the Channel Access (epics) to communicate with a VME Crate. For
this i put monitor-functions with ca_search_and_connect, ca_pend_io,
ca_add_event and ca_pend_event. The program already works, but after a
time (~ 2 h) the monitor-functions just disconnect and the program
abort. I can restart the program without any problem.
When i reboot the Crate the program works on, so i can say it's no
problem with the network connection.

The message i get is the following:

CA.Client.Diagnostic.....................................
	Message: "Network conncetion lost"
	Serverity: "Warning" Context: "test1:5064"
	Source File: ../iocinf.c Line Number:1504
.........................................................

I had looked into iocinf.c and i think there is a counter, who
disconnect the monitor-function. Why?

So, if you have an answer please let me know.

John
