hello, i'm running epics on a linux softioc and get the below error message after the ioc sits for a while. the application was built with epics base 3.14.18.2 and with the following synapps modules/versions (if it matters): autosave - 4-2-1 asyn - 4-9 calc - 2-6-3 motor - 6-4-2 seq - 2-0-11 sscan - 2-5-6 std - 2-6 ----------------------------------------------------------------------------------------- medmCAExceptionHandlerCb: Channel Access Exception: Channel Name: Unavailable Native Type: Unavailable Native Count: 0 Access: Unavailable IOC: Unavailable Message: Virtual circuit disconnect Context: ioc26idbpol.cnm.aps.anl.gov:5064 Requested Type: TYPENOTCONN Requested Count: 0 Source File: ../cac.cpp Line number: 1142 ----------------------------------------------------------------------------------------- basically, i ssh into the machine through exceed and launch the medm screens as well as the ioc (interactively). if i just let it sit, then after a few hours (i've seen it fail after ~2hrs and sometimes after 5hrs) the ioc returns to the linux shell prompt (bash) and the above message appears (no other messages). has anyone seen something similar, know the cause, and resolution? ideas? any help is appreciated. please advise,thanks in advance, /david -- +-------------------------------------------------+ David M.
