What does the following neo4j error mean?

I'm trying to run some queries on the date I've imported (while the rest are being imported) into neo4j but I'm getting the following error:

Something went wrong: "Error: Reference.set failed: First argument contains a string greater than 10485760 utf8 bytes in property 'users.auth0|5aeb486d249b5d6bdbe1a2d5.grass.0.data' ('{"0":"{","1":""","2":"0","3":""","4":":","5":""...')" and the application can't recover.

It doesn't happen all the time. When it does, I restart the PC, wait a bit and then queries run again until they don't. Meanwhile data are being imported while I process the already imported data.

PC specs:

  • core i5
  • 16GB RAM
  • 1TB HDD

OS: Ubuntu 18.04.1 LTS

Any suggestions?
