[Solved] Timer already canceled error

  • Hello everyone,

    I'm having difficulties with meta points using a CRON patern.
    As soon as I disable them, if I enable them again the message "Timer already canceled" pops up and all meta points with CRON stop being updated.

    I'm running Mango under Ubuntu 10.04LT with Tomcat6 downloaded from Mango website.

    Have some of you run into that issue?

    Thanks for your help

  • I can't recreate. Is there an error message with stack trace in the Tomcat console? Also, what version of Mango are you using?

  • Thank you very much for your answer mlohbihler,

    I have put a log extract just when the error occurs (2010-11-14 21:18:37,306) in the attached file.
    In the beginning of the Catalina log file I can see the Tomcat version:
    INFO: Starting Servlet Engine: Apache Tomcat/6.0.20

    I can see also an info at beginning of log file, could it be linked to the problem?
    INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/lib/jvm/java-6-openjdk/jre/lib/i386/client:/usr/lib/jvm/java-6-openjdk/jre/lib/i386:/usr/lib/jvm/java-6-openjdk/jre/../lib/i386:/usr/java/packages/lib/i386:/usr/lib/jni:/lib:/usr/lib

    I have read there was a bug in Tomcat 6.0.24 causing the same error message but I'm not sure it is linked:

    Thank you for your help,

  • If nothing helps:

    First Install sun-java6-jdk
    Second deinstall any openjdk and gcj stuff - you have now a clean java system. I had some difficulties with openjdk6 after installing suns jdk and removing openjdk its working.


  • Is this still an issue?

  • Hello mlohbihler and apl,

    I have installed Sun Java, removed OpenJava and Mango has been running without issue since then.
    I believe the issue is definitively solved.

    Thanks a lot!! :D
