RGB composition problem

I usually get a composite RGB image from Sentinel2 products, but today I started having problem with a certain combination (made by me and saved as an additional one)
The error I got are in the logfile I add heremessages.log (87.3 KB)

This came out suddenly while trying to visualize different kind of images and now the error is always appearing.


Hi Antonio,

strange that this happens suddenly. The reason is not clear to me. It seams to be a multi-threading issue. Such issues can occur sometimes and sometimes not. But strange that it happened never before and now always.
Your are still using SNAP 6, maybe updating to 7 could help.
