Explanation of invalid argument -Xmx512m in error log

Each time I run MoneyDance under Ubuntu the message "invalid argument -Xmx512m" gets posted as the only line in the error log. I have detected no problems whatsoever with the program. I'm quite happy with it. I'm curious about the invalid argument however and wonder if I should be concerned. I'd appreciate any enlightenment. I'm running MoneyDance 2008r4 (640) under Ubuntu 8.04.

    what JRE are you using?

    The java argument -Xmx512m normally helps to resolve unpredictable problems as it enables more heap memory than with standard setting. I've found that esp. Sun JAVA exposes some problems when creating/showing graphs and there is not enough heap memory.

    Hello Robert,

    thats quite interesting, as I use Ubuntu Gutsy (7.10) with Hardy's SUN Java (build 1.6.0_11-b03) and I don't see the mentioned error in the logfile.

    Try "java -X" on a commandline to see if this non standard argument is still supported; Btw. are you sure the mentioned runtime is used as default and not Sun JRE 1.5 or OpenJava?
    You may check that taking a look into MD's menu point "help" or again on commandline with "java -version"

    But as long as you don't have any problems displaying graphs you may ignore the error message.

    MD help tells me "Java Version: 1.6.0_05
    "Java Vendor: Sun Microsystems Inc."

    java -X reveals: "-Xms<size> set initial Java heap size"

    I have 2G of memory installed on my laptop. Perhaps 512m is too large
    or maybe I should upgrade Java. Every feature of MD, including graphs,
    seems to be working fine. In fact, I've decided that should Quicken
    release a Linux version, I would not go back. MD works great for me,
    especially since I can export reports to a .csv file and do whatever I
    please with the data. But I appreciate any comments you may have about
    the "invalid argument!"

    I was getting the same message in the error.log on my ubuntu machine and so I checked in with the developer. He thinks it means that the parameter to set the maximum heap limit in the java VM wasn't recognised. It may have been passed incorrectly by the start up script, or maybe the JVM doesn't support that format. Either way its nothing to worry about and the developer has put it on his task list to fix it.

    Hi all,

    I am getting a similar error in the error log when I start Moneydance (640) on a Windows XP Pro machine. For me however, Moneydance wont even start. I the initial banner but nothing further happens...

    Is this the Java heap memory issues people have been mentioning?

    How can I fix it?


    PS: The exact error I get is: -Xmx1024m

    Sounds more like the problem with MD closed while minimized...
    I believe Moneydance starts up and is running - you just need to select it's window list entry and use RMB+Maximize to get MD back visible...
