Yes. This is a known issue due to session timeout. stevegyc,
I guess you are clicking tryit from Management Console Service overview page, which has a chart showing statistics. When you go to try it page, the session expires on the admin console. That's why you are seeing the error on the console. I hope this is clear. There are many issues reported for this also [1] [1] https://wso2.org/jira/browse/WSAS-1549?jql=text%20~%20%22ERROR%20org.wso2.carbon.statistics.ui.StatisticsAdminClient%20Cannot%20get%20service%20stats%22 On Wed, Mar 12, 2014 at 7:29 AM, Iranga Muthuthanthri <[email protected]>wrote: > Hi, > > The possible reason for this excption could be a session time out, which > is not specific to DSS.
