    Default 2 issues : Java settings and log files

    Hi, I'm working out of my area here, so apologies, for what might be a basic question.

    1: Java settings

    Our install of WMS will only run with the heap set at a max of 2500M

    manually I get

    -bash-4.1# ./startup.sh c
    Error occurred during initialization of VM
    Could not reserve enough space for object heap
    Error: Could not create the Java Virtual Machine.
    Error: A fatal exception has occurred. Program will exit.
    Or OK at 2500M

    -bash-4.1# ./startup.sh c

    So I'm looking at support and the above, is this failing because it's 32-bit, should I be setting java at a max of 1800M?

    2. Log files

    We've also had problems with servers running of disk space. And found the folder with all the wowza logs to be the problem, I just deleted one with 3Gb of logs.
    Is there a way to automatically clear old logs? Either that or it's manually clearing them or turning them off?

    Thanks,
    Danny.

    Default

    Hi Danny,

    It is recommended to use the latest version of Sun Java JDK (Java SE Downloads) and it is best to run a 64-bit operating system with the 64-bit Java VM.

    However, if you are running a 32 bit system, then it is recommended to use a Heap Size of 1500MB, and not to exceed 1800MB.

    You can find out more about these settings here:
    How to do performance tuning

    As for the logging question, there is no built in way to delete old log files that I know of. You can manually delete them or you can turn them off by commenting everything out in [wowza-install-dir]/conf/log4j.properties.
