    There is no-one disputing that people are having this problem. It doesn't matter how many people are having it. We still need the same high quality debugging information to be able to solve it. Just telling us that more people have the problem does not help solve it in any way.

    Now, what is this "memory limit error" that you are talking about. Can someone please supply screenshots of these things?

    I dont understand why would you start a new thread asking for help w/ preware instead of asking the DEV in his own thread?

    I mean who better to ask than the guy who wrote and tested the software.
    Please hit the thanks button if I helped you

    If you've enjoyed my patches please feel free to donate towards further development.

    I believe he means that the app catalog will say the memory is full, even if you have nearly 0 apps installed. I ran into this issue also when I had Package Manager installed. It is the same error message you would receive if the phone was truly full.

    OK, I have now been able to reproduce this problem.

    If you are on the Linux command line, and type:

    Code:
    luna-send -n 1 luna://com.palm.appinstaller/queryInstallCapacity '{"appId": "com.jason.app.lemonade", "size": 2805.083984375}'
    You can make the Pre UI hang for 30 seconds. If you also type "ps -ef" continually on another terminal connection to the Pre, you can see the "ipkg -o /var list" command being executed by the Palm appInstaller code.

    So, the problem is in the Palm appInstaller code, not in the Package Manager Service. During that time, the Package Manager Service is installed, but is not active, and has no methods being called by anything else.

    Now, it is true that the Package Manager Service is involved. The way that it seems to be involved is due to the number of available packages we have in the feeds.

    Try the following:

    1) Go into the Preference screen of Preware.
    2) Hit the FEEDS button top-right
    3) Turn OFF all the feeds

    Then try the above luna-send command again. The "hang" is reduced to about 1 second.

    My guess is that there is very inefficient code in the Palm appInstaller service which is doing something with the output of the "ipkg -o /var list" - which is restricted to the number of packages installed on your Pre when all feeds are disabled, but reports the complete set of all available packages (671 at the moment) when all feeds are enabled.

    I expect they actually intended to call "ipkg -o /var list_installed" (which only reports the packages installed) to check the available space relative to the size of the /var partition, but they are actually now calling "ipkg -o /var list" (which reports *all* available packages), and this is probably the reason why people are seeing out of memory errors (since it is adding up the size of all *available* packages, instead of adding up the size of all *installed* packages).

    So, the work-around is to go into Preware and disable all the feeds before doing anything with the Palm App Catalog.

    We will work out a means of installing homebrew apps, plugins and services which avoids this issue.

    My guess was correct. See http://forums.precentral.net/web-os-...g-hanging.html for the analysis, and please continue discussion of this Palm App Catalog problem in that thread.

    The work-around is to go into the Preware Preferences screen, hit the “Feeds” button in the top-right corner, and disable all the feeds while you use the Palm App Catalog application in another card. No need to exit the Feeds screen, just toggle all the button to “Off”, and then toggle them back to “On” when you’re finished with the App Catalog.

    We will work out a longer term solution in the next few days, and I suspect we will be able to implement it in the next version of the Package Manager Service.

    Can you confirm whether the memory limit error occurs if all the feeds are disabled in Preware?

    I disabled all the feeds in Preware like you suggest, it doesn't freeze anymore but still gives me the "Sorry, Not enough memory, please delete an application you have installed to make room." error...

    From Preware: 27 apps, 2 linux apps, 36 patches, 3 services, 1 theme, 9 unknown.

    From the apps catalog; less than 10

    Oh, you're coming up against the existing known problem with the Palm App Catalog, not the new memory limit problem that splmonster was referring to.

    See the many other threads on PreCentral on how to work around that one.

    But I didn't have that problem before the new Preware version??

    There could be any number of reasons (e.g. emails received, log messages, etc) which could push you over the free space limit that Palm imposes.

    Unless you can reproduce the problem with less than 20 packages installed, then it's the same problem as before, not a new problem.

    Does the Default Theme have to be uninstalled? Or just ones you've added.

    You were right, sorry about that.

    I went down to 18 apps. Did a reset. Then in the Apps catalog I hit download for an app . It froze fo 40 secs (I didn't uncheck the feeds in pref), but it started to download after.

    I finally found Luna Manager! It wasn't showing up in Preware, but I found it in Preload! Nothing is wrong with my Package Manager Service or Preware, but when I restarted JAVA with Luna Manager (which appears as though I never even needed) I got the same error that everyone else seems to be getting "Package Manager Service is not running"! My theory is that this is an incorrect error with Luna Manager or that when the network connection restarts it stops running the Package Manager Service thus giving you the error. My advice is to ignor this message!

    Is it just me or does the new update of Preware from yesterday cause quite a few apps to show up in an "unknown" category? Does anyone know why?

    Yes, that's intentional.

    Any packages that are currently installed, but do not appear in any of the Feeds enabled in Preware, will show up under Unknown.

    Rod, thanks so much for all of the work you guys do and the trouble you go through (like doctoring your Pre) to make our lives better!
