Anyone know what this value means? I was running in quiet mode so no other indications.
My suspicion is that exit status 15 means 'exit status -15', which means 'the process was terminated' - usually this means the computer ran out of memory and decided to kill ecm. You're right that +15 is not a valid configuration of set bits for a gmp-ecm status.
