sceenshot, it is not clear why the STARTABORT transition was initiated.

So there is no error on run start anymore? To debug the stuck run stop, please use "stop -v"
to see where it got stuck. You can also play with the RPC timeouts (the connect timeout and
the response timeout), to make it get "unstuck" quicker. Definitely it should not be stuck

 02 Mar 2021, Konstantin Olchanski, Info, shortest possible sleep
|
since I am implementing a polled equipment, I was curious what is the smallest possible sleep time on current computers.
in current UNIX, there are 2 system calls available for sleeping: select() (with microsecond granularity) and nanosleep() (with nanosecond granularity).

UNIX/POSIX advertises functions for sleeping in microseconds and nanoseconds,

Interesting. Run start/stop from odbedit works but from mhttpd gets stuck.

well, if this is something in ROOT, perhaps you can pursue it with the ROOT crowd,
they are quite friendly.
