Timed out while waiting for an event

[admin]

Hi,

we are work with DS6, we have detected an error in Job Sequencer, our job had stopped with :

CADEIA01..JobControl (@JOBA_S):
Controller problem: Error calling
DSRunJob(JOBA), code=-14
[Timed out while waiting for an event]

We check the our job and it had finished with no errors.
We check the timeout in our project and it is with "no timeout"

What could originated this error ? Why our job sequencer could not detected the finished of our job ?

regards
RMS
