Our Appian 7.11 demo system was running fine till yesterday.
We tried restarting the system today and got the following error.
Looking for help on how to resolve this.
Attaching the JBOSS log file as well.

  • Please check the permissions on the folder. The user that is running Appian on the server should have full read, write, and execute permissions for <APPIAN_HOME> and all subfolders and files. After you've checked that, with the application server stopped, please do the following:

    1) In <APPIAN_HOME>/ear if the marker files reads "suite.ear.undeployed" or suite.ear.failed", please rename is to "suite.ear.dodeploy".
    2) Manually clear the osgi cache by deleting the contents of D:\\Appy711Trng\\ear\\suite.ear\\web.war\\WEB-INF\\osgi-cache .
    3) Start the application server

    Let me know if you still encounter the issue after performing these steps. Thanks.
