3 months ago As a follow-up, I tried running a different dataset and saving the output to a network disk that has TB of free space. I got essentially the same error:

Light curve fitting (Stages 4-6)
What happened?
During stage 5 light curve fitting I suddenly start getting warnings about "No space left on device". Output files keep being written, but eventually Eureka! crashes. A df when the warnings started appearing and after the crash show 5 GB still available. Rebooting and trying again with nothing running but iterm and Eureka! produced the same results.
