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.
