Hi Stephanie,

Many thanks! According to your recommendation, I have added some delay between each state machine run and I cannot reproduce my problem for now. For your information, it was not the same sequence, but many different sequences on the same SoftIOC. And the problem appeared most of the time on the last ones.

I will also test the candidate release as proposed by Ben.

Cheers,
Nadine

Hi Nadine,

Do you activate more than a few programs using the same sequence on one soft IOC?  I had a similar problem last year when moving some state programs from an RTEMS IOC to a linux IOC and found that putting a delay between activations helped:

...
seq(&psControl,"ps=GTL-ALPHA,limit=Des")
epicsThreadSleep(1)
seq(&psControl,"ps=GTL-Q1F,limit=Des")
epicsThreadSleep(1)
seq(&psControl,"ps=GTL-Q2D,limit=Des")
...

I never got a chance to debug further.  Probably something specific to my set up but your symptoms are the same.
