Hello [~joewitt]
Have you got any news?
I have upgraded 10 NIFI instances in standalone or cluster node. All have the
same issue
{code:java}
Caused by: java.nio.file.FileSystemException:
./provenance_repository/lucene-8-index-1637634601351/_14g8_Lucene80_0.dvd: Too
many open files
{code}
And only workaround is remove all files in the repository, remove old logs, an
restart the NIFI.
Please help us
