[Solved] What is this?

Seems like a Java error. I notice you're using a temp directory, is this located somewhere with limited space? If so, could you try it on a different location and with the latest APP 1.072 version?

I just installed APP and am trying to create a stack of 100 subs.

At the integration phase I get this:

Hi @arie & @vincent-mod,

Thank you Arie for reporting the issue.

Please check the release notes of APP 1.072 ;-), this bug mainfests itself on integration on certain external drives and it is apparantely caused by IO errors on the Operating System level. In APP 1.072 this bug is caught so it should not happen again.

FIXED, Integration MemoryToFileMapper, in some cases, a Buffer Underflow exception could occur while integrating frames. This seemed to happen only very infrequently, mostly with very large datasets (100s of frames)  and usually an external harddrive was involved. It was reported to happen on both MacOS and Windows, not on Linux as far as I know. I have made several adjustments now to prevent the exception from happening and if it still does happen (due to an Operating System level IO error), it will be caught cleanly now so the integration can still continue. The issue was reported recently here : https://www.astropixelprocessor.com/community/main-forum/what-is-the-best-way-to-combine-multiple-sessions-over-time-other-then-redoing-all-every-time/#post-4991 Theoretically, there is also the possibility of a BufferOverflow Exception, but that never happened as far as I know, anyway, if it does happen, it will also be  caught cleanly now so the integration can still continue. Both exceptions should never occur again while integrating.

Kind regards,

Mabula
