From the little I could make from the screenshot it was a SIGABRT which might very well be an out-of-memory situation you are running into. Did you use any unusual modules on those images? Please look at "top" while exporting to see if dt starts to eat all memory. Another thing to check is if you are using OpenCL and if turning that off fixes it. And check your system log or "dmesg" after dt crashed to see if anything about oom is mentioned. Anyone else having ideas? > > Regards, > > J.-Luc Tobias [...]
