> I had some nifi nodes crash last night with errors that suggested file handles where exhausted. When I looked into lsof, I found tens of thousands of open file handles to a public key I was using in EncryptContent.
> It looks to me like the OpenPGPKeyBasedEncryptor.getPublicKey leaks file handles. Because this is called in EncryptContent's validate method, these file handles build up even when there is no data flow. You can reproduce by the following:
> * Create a PGP public key
> * Set up an EncryptContent processor with the public key for PGP encryption.
> * Do lsof | grep publicKey and see the file handles build up.
> I have a patch. Will post a pull request shortly. I have no idea how to test it though other than that I ran it locally and the file handles stopped building up when I used the patched code.
