That does sounds like a possible cause.
Do you have long running code with multiple queries or some sort of heavy
reporting query of some sort?
Network interruptions? Latency?
Do you always have the CF monitor running? If so, try to turn off all the
monitoring as that was buggy in CF9 if I remember correctly (JVM killer).
Just naming a few options to think of. Good luck.
