there is a small problem with the TikaParser. Currently version 1.14 is used in Knime. If you separate big data e.g. emails from their attachments, the error “Too many open files” appears after some time. Unfortunately I don’t have the link at hand where this bug is discussed and it was marked as fixed in later versions.
As a workaround I have now downloaded and overwritten TikaParser version 1.18. Would it be possible to do the same in the next Knime version?
We’ve updated Tika to version 1.18 in our nightly build. As we were not able to reproduce the issue it would be great if you could give it a try with the nightly build and provide some feedback.
I’m happy to hear that it works with the updated Tika library. Unfortunately this change will only be available with 3.7 and not as part of the upcoming 3.6.1 release.
