Hi Keith,
Last week I discovered a possibly related issue with processes not waking up.
I have a process, p1 which runs in a loop, executes some code and delays itself
for a certain time.
code:
//Method1
<>abort:=False
<>p1:=Current process
$delay:=30*60 //beep every 30 seconds
Repeat
BEEP
DELAY PROCESS(<>p1;$delay)
Until (<>abort)
Just start Method1 as a new process and open the runtime explorer to watch the
status.
If another method pauses p1 and resumes it within the remaining delay time, the
process p1 status goes from delayed to paused. This way p1 stays paused until
it gets a (second) resume from somewhere else.
Eg:
PAUSE PROCESS(<>p1)
RESUME PROCESS(<>p1)
TRACE
<>abort:=True
If this code is run (pause immediately followed by resume) while the status of
p1 is delayed, the process will stay in status delay until the delay time has
passed and then change to paused.
This worked fine in v15. I don’t know if this is actually a bug, but here is a
change in behavior between v15 and v16.
In v15, when running pause and resume, the (delayes/paused) process continues
immediately (beeps) and then waits again in the next delay.
Its like in v16 resume process does not work correctly when a delayed process
is paused.
In my project I found a work around, I did not report a bug.
