Too many open files during report-execution

[Tobias Horsmann]

Hi,

I have a project that uses N Pos-Tagger to tag N Corpora. Each pair of tagger-corpus produces a handful of result-files. When my reports are executed I get an exception saying I have too many files open:

I have three or four reports each reading in some of those files. It seems like Lab keeps the file permanently open in the background?

As far as I am concerned, I don't want those file to be kept open. I could try to increase the OS limit of open files, but I would prefer when Lab would close the files? Is this somehow possible?
