    Hello,

    Having cPanel installed on our server with Apache-Tomcat 5.5.35.

    When we observer it crashes many times and every now we have to restart the Tomcat and then only it starts.

    Found below log in catalina.err.

    WARNING: Servlet jsp is currently unavailable

    Don't know whether is because of older version of commons-lang.

    ============================================================

    Even found below log, of missing SESSIONS.ser.

    SEVERE: IOException while saving persisted sessions: java.io.FileNotFoundException: /usr/local/jakarta/apache-tomcat-5.5.35/work/Catalina/dadarmath.com/js/SESSIONS.ser (No such file or directory)
    java.io.FileNotFoundException: /usr/local/jakarta/apache-tomcat-5.5.35/work/Catalina/dadarmath.com/js/SESSIONS.ser (No such file or directory)

    For which received suggestion to give read/write permissions to that particular folder so that SESSIONS.ser will get created and all sessions will get stored before restarting tomcat.


    Please suggest is it correct solution. for Tomcat crash?

    ==============================================================

    Even found one more solution in below forum to change reloadable="false" in server.xml file.

    http://forum.springsource.org/showth...ervlet-reloads

    Please suggest which option should I try or it is something different issue.

    Thanking you,

    Please suggest,
