Thanks for your detailed explanation.

I am trying to look through base-3.14.*/src/misc/iocInit.c. I guess
the only function related to caRepeater would be rsrv_init(). Then I
take a quick look at src/rsrv/caservertask.c, but still don't see how
the caRepeater get spawned. Could you tell me how the caRepeater is
started during iocInit? Also what does "rsrv" mean / stand for?

Thanks again,

Jack
