JPPF 5.9 - java.io.EOFException #6

Open pparthenhs opened 4 years ago

pparthenhs commented 4 years ago

I am using Dockerized version of JPPF 5.2.9. The driver is working perfectly but the nodes cannot connect successfully.

In more details on jppf-node:

  1. On docker logs

In other hand on jppf-driver

  1. On docker logs

  2. On jppf-driver.logs

The most recent ISSUE I found is the following but I am not sure if that is still relevant https://www.jppf.org/forums/index.php?topic=7930.0

Any ideas or suggestions are welcome.
