Are your solenoids firing on their own?

Team 188 is trying to track down a pesky problem that ultimately results in SOME of our Festo Single Solenoids randomly firing once in a while.

Please post if you have Single Solenoids installed on your robot, and have experienced them randomly changing state, and meet the following criteria:

1) The solenoids that fire on their own are single solenoids

2) They only behave erratically when you try and keep and hold them in the energized state - if you keep and hold them in the non-energized state, they stay perfectly still

3) You notice the Spike controlling them DOES change state for no reason (The lights blip orange when they should be Red/Green/Off)

4) You can simulate the weird behaviour by quickly disabling your robot, then re-enabling it

5) Whenever the solenoid fires on its own, you notice that the Radio Modem light on the RC flashes red for a fraction of a second

I have posted another thread in the Control System forum, however I posted this message too because there may be teams desperately trying to troubleshoot what they think is a pneumatics issue.
