HI All 

See https://community.progress.com/community_groups/openedge_deployment/f/21/p/57655/202570#202570

I have just tested clustering in 11.7.5 and the bug in the content.xml still exists.

If you want clustering to work correctly you will need to comment out manager e.g.

<!-- CJB Comment out for Clustering
<Manager
maxActiveSessions="-1"
pathname=""
processExpiresFrequency="6" >
<SessionIdGenerator sessionIdLength="22" />
</Manager>
