Hello,

 

Recently our Maddash server has ran into some complications. While the toolkit side of the node is exhibiting no issues, testing seemingly isn’t effected , and I believe I have found the cause of the issue.

 

# systemctl status maddash-server

maddash-server.service - MaDDash Scheduler and REST Server

                Loaded: loaded (/usr/lib/systemd/system/maddash-server.service; enabled; vendor preset: disabled)

                Active: failed (Result: exit-code) since Sun 2018-08-05 15:44:15 EDT; 18h ago

               Main PID: 1287 (code=exited, status=1/FAILURE)

 

So, looking into the /var/log/maddash/maddash-server.out file, we see this:

 

Initialization error: Connections could not be acquired from the underlying database!

java.lang.RuntimeException: Connections could not be acquired from the underlying database!

        at net.es.maddash.MaDDashGlobals.<init>(MaDDashGlobals.java:185)

Has anyone else ran into this issue? ( Or, it’s entirely possible this is a redherring. )

 

Best,
