Thanks Lucas. The Bug id is 2978990.
In my example I just using "ping localhost" to pretend a long time run script.
ping localhost never end unless the process is being killed. And it's hard to
estimate the time of our test script, so I can not set a timeout to the
command. That why I ask help here:) Very appreciate.

Open a bug and we'll get this problem fixed. It has to do with the target
machine never sending a message that the process completed or terminated
due to STAFProc never being shutdown properly before the reboot occurred.
But there are other ways to work around this issue. For example, instead
of using the PROCESS service to run a system ping command to ping the
target machine, use the STAF PING service as following to ping the target
machine:
STAF targetMachine PING PING
This STAF PING request should fail if the target machine is rebooted
before the ping request completes.
Or, you really need to use a PROCESS START request to ping the machine for
some reason, specify a maximum wait time, e.g. WAIT 1m) so that the
PROCESS START request will timeout if the command does not complete within
45 seconds (or whatever time period you want to specify):
STAF targetMachine PROCESS START SHELL COMMAND "ping localhost" WAIT 45s
RETURNSTDERR RETURNSTDOUT

[staf-users] STAF did not return if reboot the other machine.
Hi all,
I meet a problem when using STAF in Linux.
I try to use STAF to run some long time script. But during the script
running if I reboot test machine STAF will hang up and did not return
forever.
The STAF version is 3.4.0
For example:
1. #STAF targetmachine process start shell command ping localhost wait
returnstderr returnstdout
2. Then I reboot targetmachine. The STAF command will hang up and never
return.
I think it should end and return some thing like this.
Error submitting request, RC: 22
Additional info
---------------
STAFConnectionReadUInt: Error reading from socket: other side closed
socket: 22
This message will show if I kill staf process on that machine. I think
reboot machine also will kill staf process.
Thanks,
Yang
