> We have an application using Tika which parses roughly 7,000,000 files of 
> different types, many of the files are MSG files with attachments. This works 
> correctly with Tika 1.9, and has been in production for over a year,  with 
> parsing runs taking place every few weeks. The same application runs into 
> insufficient memory problems (java heap) when using Tika 1.13.
> I have used lsof and file leak detector to track down open files, however 
> neither shows any open files when the application is running. I did find an 
> issue with open files https://issues.apache.org/jira/browse/TIKA-2015, 
> however there was a workaround for this and this is not the issue.
> I am sorry to have to report this with a level of vagueness, but with lsof 
> turning nothing up I am a bit stuck as to how to investigate further. We are 
> more than willing to help by testing on the basis of any ideas provided.
