[Erik Salter (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12649649#comment-12649649 ] 

Erik Salter commented on ISPN-1602:
-----------------------------------

Bela, thanks for the comments.

A few things:

- No, I'm not using RELAY, just TopologyAwareCH.  Those site identifiers are node names.  Rest assured RELAY testing will commence soon.
- I removed FLUSH.
- 500ms is for young generation GC.  We only run a full GC when the heap is full.  This test is only designed to fill up at most 2-3GB in heap space.
- You convinced me -- need to use your stock config. =)

>          Components: Core API
>    Affects Versions: 5.1.0.CR1
>            Reporter: Erik Salter
>            Assignee: Dan Berindei

> During load testing of 5.1.0.CR1, we're encountering JGroups 3.x dropping views.  We know due to ISPN-1581, if the number of view changes > 3, there could be a stale lock on a failed commit.  However, we're seeing stale locks occur on a single view change.
> In the following logs, the affected cluster is the erm-cluster-xxxx
> (We also don't know why JGroups 3.x is unstable.  We suspected FLUSH and incorrect FD settings, but we removed them, and we're still getting dropped messages)
> The trace logs (It isn't long at all before the issue occurs) are at:
