First, thanks to Matt Newville and Mark Rivers for your help in getting my XSPRESS3 IOC running. (I'll post later it it actually fixes our original problem.)
I have two questions related to the IOC:
On IOC start-up I get 48 messages (6 channels x 8 SCAs) of this type:
devAsynFloat64Array::initCommon, XSPRESS3:C1SCA1:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found
devAsynFloat64Array::initCommon, XSPRESS3:C1SCA2:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found
devAsynFloat64Array::initCommon, XSPRESS3:C1SCA3:TSArrayValue connectDevice failed asynManager:connectDevice port XSP3.C1SCA_TS not found
.
.
.
Plus this message:
2020/01/28 12:57:33.650 asynNDArrayDriver:readNDAttributesFile: unknown attribute type = INT for attribute CHAN1DTCFLAGS
Any advice would be appreciated.
Thanks,
John

Matt,
Thanks, I knew nothing about the /dev/shm/xsp3* bit. That did the trick. The IOC now starts
and connects.

Do you have and are you loading Xspress3 settings and calibrations files for 6 channels or for 4 channels? Somewhere in the IOC startup, you have to define where these settings files
are, with something like
dbpf("$(PREFIX)det1:CONFIG_PATH", "/home/xspress3/xspress3_settings/current/") And these settings really should be for the correct number of channels. If you change the number of channels I believe you need to remove the shared memory files in /dev/shm/xsp3*.
These files will be re-created when the IOC restarts the xspress3 server.
