Experimental Physics and
Industrial Control System

Hi,

I seem to have such a problem: when my IOC starts up, some of my records
want to callback almost immediately.  Then my IOC crashes, because the "onceQ"
related stuff are not created yet -- is this possible?

Is it safe to move the "scanInit" call in iocBuild to just before "initDrvSup"
(EPICS base 3.14.12, src/misc/iocInit.c)?

Thank you for your advices!  Best regards,
Dehong
