RunTime Error: Sequence doesn't see Parallel execution

[sangi1981]

Hi all,
I have a multiistance sequence that invoke multiistance parallels.
Some times, it happens that an execution istance of sequence goes in error.

If I search in log, I find that abort is due to a call of a job parallel:
1) It happens that job parallel istance goes,
2) sequence stays in waiting,
3) and then it appears a "Not Running", 99, error.
4) At this time, sequence aborts.
5) But Job parallel goes and terminates correctly after few times.

This kind of error not happens with regularity, and not on same runtime invocation istance; but it happens ever at same point in sequence flow, at same job parallel invocation, that is after many others.

I hope to be clear in my explanation.


Is there any known issue related to the SunOS, or similar?
It seems that job sequence looses control of job parallel.
This time, there was many jobs running; I don't remember status of machine last time the same error happened.

Thanks in advance
