Applies to:Oracle Coherence - Version 3.6.0 and later
Information in this document applies to any platform.
There are multiple Coherence nodes configured to run on the same machine all with tangosol.coherence.localport.adjust=false.
Node 1 can be started with no error, but on trying to start Node 2 the following exception is reported:
Trying with different port combinations for Node 1 and Node 2 gives different results:
6000/6001 -- fails
6600/6601 -- fails
6000/6601 -- works
6600/6001 -- works
6000/6002 -- works
6600/6602 -- works
This used to work fine until Coherence 3.6.0 Patch1, but is failing in Coherence 3.6.0 Patch2 and later.
