Jens Deppe commented on GEODE-10004:
------------------------------------
Geode has other 'server' components that could all produce conflicting port
issues - WAN gateways, JMX, http and memcache come to mind.
> Starting server should fail fast when server port and redis port are the same
> -----------------------------------------------------------------------------

> Key: GEODE-10004
> URL: https://issues.apache.org/jira/browse/GEODE-10004
> Project: Geode
> Issue Type: Bug
> Components: gfsh, redis
> Affects Versions: 1.15.0, 1.16.0
> Reporter: Hale Bales
> Priority: Major
>
> When starting a cluster with GFSH with geode-for-redis enabled, starting a
> server fails when the geode-for-redis-port and server-port are set to the
> same port. It fails with the below stacktrace, but does not fail fast. We
> should be able to detect this issue before we reach the point of getting a
> bind exception.
> stacktrace:
> {code:java}
> Exception in thread "main" java.lang.RuntimeException: An IO error occurred
