Hi Kamil,
What model are you using here? Zookeeper or file system?
Is it possible that your first agents process has not finished shutting down
before you try to start it again?
In any case, I suggest you try upgrading to MCF 1.7.1, since fixes were made in
this area.
Also, lock clean procedure will only work if the processes fully shut down
before you do it. ALL ManifoldCF processes must be shut down, then do the lock
clean, and then start processes up again.
Thanks!
