Philipp Bracher commented on MAGNOLIA-2172:
-------------------------------------------
I was able to investigate the system by using the shell. So we can say that the
node /expressions/activation/xxxx can't be saved because the parent was
modified externaly. As soon I refresh the session (by using the new
LifeTimeJCRSessionUtil) the system starts to work again.
I don't know how it could happen that the content was modified externally as we
use a single session. It might be that the problem lays in the fact that the
jackrabbit sessions are not thread safe while writing (at least that is my
status).
So I will patch the workflow module in a way that it uses unique sessions per
atom operation (store, fetch, ...). You can then run it testwise in your
instance (redoing the loadtest).
I also noticed that the connection to the database was reestablished now and
then (should not have an impact on that but you never know)
