Error while firing WatchedFolder trigger

Mar 11, 2008 11:34 PM

Hi all,

Once every day the server reports the following error and cannot recover (needs restart):

2008-03-10 22:36:50,855 ERROR [org.quartz.core.ErrorLogger] An error occured while firing trigger 'WatchedFolder.WatchedFolder:605'
org.quartz.JobPersistenceException: Couldn't select trigger state: Communications link failure due to underlying exception:

I have just reinstalled the server and imported the processes I had created earlier, but no custom setup within the "stomach of JBoss/LiveCycle".

Does anybody knwo what I can do to rectify/localise this error?

Sincerely
Kim

    Can it really be true that nobody knows anything about this problem?

    The problem seems strange to me that this problem occurs - as I can only find one watched folder endpoint in the Administration UI - and the error occurs even if I have disabled this endpoint.

    Any suggestions to what I can do to chase the nature of this error?

    Thanks in advance

    Sincerely
    Kim

    Report
    From the LiveCycle ES Error Code Reference

    Extended periods of server inactivity when using JBoss
    Application Server configured with MySQL (the JBoss
    turnkey). The exception is raised by background
    processing during internal database management. Its
    presence is expected: Idle connection with the
    database times out and causes the TCP/IP connection
    to close. Exceptions typically occur after 8 hours or
    more of inactivity in LiveCycle ES.
    [Exceptions seen on JBoss/MySQL and start with:
    java.sql.SQLException: No operations allowed after
    connection closed. Connection was implicitly closed
    due to underlying exception/error: ** BEGIN NESTED
    EXCEPTION
    **com.mysql.jdbc.CommunicationsException
    MESSAGE: Communications link failure due to
    underlying exception: **java.net.SocketException
    MESSAGE: Software]

    The document also says
    This exception does not
    impact the LiveCycle ES
    server processing and
    can be ignored.

    However, I also need to restart the server to get it working again.

    Sincerely,
    Nick

    Report
    We had a problem with LC ES on jboss with MySQL. I believe the problem was that after the server being idle for a while, the connection to MySQL could not be restored untill the server was restarted. This was reported to Adobe, and a patch was made. Try contacting Adobe support and ask for the patch. It may help you.
