We are using OrientDB 2.0 - M3 we are also doing all our persisting through
spring-orient-data and we see this message frequently but not
deterministically. I.E we dont get it every time we save.
We have reduced the web server down to a single thread using
server.tomcat.max-threads: 1
We are also certain from test cases this does not occur in a single
threaded environment and the above fix does seem to eleviate the problem.
Does anyone know what the issue have a suggested work around thoughts on
how we can trouble shoot this?
Regards Wendy
