Hi Martin,
It looks like some of the logs are full of those types of messages with various exceptions e.g. ca-mdo-server-log.txt has
2016-02-15 18:56:13,920 [EMMCacheRefresher,mdo-serverCacheRefreshCheck] ERROR null - TID[0] 5211303: Unable to process request at this time, please try again later
com.ca.emm.corejsvr.ExceptionWithNC: Unable to process request at this time, please try again later
at com.ca.emm.svcsenv.svrcommon.jmsclient.JmsMQRequester.makeRequest(JmsMQRequester.java:381)
Maybe try to stop/start all the MAA Services. If that does not help probably best to raise a Support case for us to look into it in more detail.
Thanks
Lynn
