Nine months ago, JBOSS failed with the above error, nothing had been changed. I eventually found the problem was that the server had been powered off causing JBOSS crash. I was able to fix the problem by taking the following steps: Went to the:  /usr/share/jboss/server/application/data/hypersonic Directory Deleted all the files except: localDB.script Started JBOSS and everything worked fine! It happened again on 30th December, and I followed the same steps however this time it didn't work!. I am at a loss as nothing has been changed, I believe the server may well have crashed again but the client is not telling me, and I don't have remote access at present. Thanks in advance... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/579494#579494] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
