Using "Archive the artifacts" post-build action, the following kind of issues often occurs:

Please notice that during the same run, other log files are correctly archived.

I haven't found any possible reason so far. Could such issue happen if we try to archive a file which is still being written?

Is this post-build task the correct one to use to save log files?

Thanks for your help,
David.
