Daniel Kuppitz commented on TINKERPOP3-847:
-------------------------------------------
I didn't keep a copy of the stacktraces. I will post more information if it
happens again, but this can take a while. The day, when it happened, I started
dozens of very long running (1h+) jobs.

> Key: TINKERPOP3-847
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-847
> Project: TinkerPop 3
> Issue Type: Bug
> Components: console
> Affects Versions: 3.0.1-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
> Fix For: 3.1.0-incubating, 3.0.2-incubating
>
>
> Yesterday, after working quite some time in the console, doing a lot of
> {{SparkGraphComputer}} stuff, I suddenly got an error: "Too many open files".
> Further attempts to start more OLAP jobs failed immediately. Then, a few more
> seconds later, the console was flooded with error messages coming from Spark
> (although I didn't do anything at this time).
> Restarting the console helped, everything was immediately back to normal.
