In my application I am using 4 different database connection with spring,
Before upgrading to wildfly 9.0.2 Final it was working fine, but yesterday from production I came to know that one database is not able to connect. and giving following exception
Caused by: java.lang.IllegalStateException: UT000010: Session not found ONaa4NC8R3y3WuYRhMjp5kD0__MXIkMtHbginKOx INFO | jvm 1 | 2016/09/21 05:53:09 | at io.undertow.server.session.InMemorySessionManager$SessionImpl.getAttribute(InMemorySessionManager.java:430) INFO | jvm 1 | 2016/09/21 05:53:09 | at io.undertow.servlet.spec.HttpSessionImpl.getAttribute(HttpSessionImpl.java:123) INFO | jvm 1 | 2016/09/21 05:53:09 | at org.springframework.web.util.WebUtils.getSessionMutex(WebUtils.java:328) INFO | jvm 1 | 2016/09/21 05:53:09 | at org.springframework.web.context.request.ServletRequestAttributes.getSessionMutex(ServletRequestAttributes.java:191) INFO | jvm 1 | 2016/09/21 05:53:09 | at org.springframework.web.context.request.SessionScope.get(SessionScope.java:88) INFO | jvm 1 | 2016/09/21 05:53:09 | at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:285)
While, I was able to connect to other databases through the application, only facing issues for accessing one of the database.
After restart of wildfly server issue is resolved, Even I am not able to reproduce it
