Had an outdoor gig Saturday night, it was pretty cold (40º F when we finished). I was running my usual setup, with a EBS Multicomp into a Genz-Benz 6.0. On the second song, the yellow clip/limit light came on (first time ever!) and I briefly lost signal. This happened about half a dozen times over the next few songs, and, not knowing what else to do, took the compressor out of the signal chain. The problem stopped. I'm wondering what may have caused it. The cold? This is the black-box "true bypass" model, set on normal, with compression and volume both set at 12 o'clock.
