Hello Lifang,

I concur with what Ralph has already said and would like to add some further
comments.

Of course, this type of message is normal if EDM looses network connectivity
with the IOC. Otherwise, what version of EPICS are you using? I seem to
recall that there were some problems with erroneous CA client library
disconnects in the very earliest beta releases of EPICS R3.14.
