Sorry Milt, I've got to go with greekdalek about low-rpm compressor stalls.

IF the bleeds were closed at idle, and/or IF variable stators too open, the engine is very likely to burp when an accel is requested. It's the result of the HPC aft stages being unable to pump away all the air delivered by fwd stages, which then find themselves overloaded and stall-prone.

But the chance of simultaneous independent failures on multiple donks is - well, just about zero...
