[jira] Issue Comment Edited: (ODE-493)
ConcurrentModificationException occured in memdao implementation of ODE
when heavily loaded
[ https://issues.apache.org/jira/browse/ODE-493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12665365#action_12665365 ]

-----------------------------------------------------------
The way to reproduce this bug is:
Firstly, create a process with correlations, that is, this process can be invoked several times(so CorrelatorDaoImpl can take its responsibility).
Then , concurrently call this process at different services exported by this process.
You will see this error soon
