Hi, looking at the exception log, it appears that your index has grown to a size (and number of files) that neo4j can't open them. The problem and solution is described here: [Linux tarball installation - Operations Manual](https://neo4j.com/docs/operations-manual/3.5/installation/linux/tarball/#linux-open-files) Hope that helps.

On Ubuntu you need to set the number of open files in `/etc/security/limits.d/neo4j.conf`.
