Memory leak in X50v

It's incredible. Here's the short story: I soft reset with nothing starting up. I go to memory settings and watch as the available program memory decreases by .01 MB per 1 to 1.5 seconds. I can literally watch it tick down.

Here's the longer story. I got my 50v and installed the programs I had on my x5, updating some programs on the way. I realized, using the pda for a few hours, that the memory would dwindle down to nothing. I had wisbar advanced 2, dashboard 2, journal bar, new avantgo, memmaid, tweaks2k2, etc. I did put a lot on it, and tweaked it before I realized things weren't right.

I first cleared off journal bar from loading, since I read it was infamous for memory leakage. When that didn't stop, I cleared off dashboard and wisbar. I have a CF card and an SD card plugged in. I don't know where all the memory is going. I will soon have to a hard reset and try it from scratch, to see if it does that then, but I have to go on a trip tomorrow, so it will have to wait. I very infrequently had to reset the x5, I have soft reset this one several times during the day.

Do you guys see this as well?

Tick, tick, tick. Damn.

i havn't had a chance to test this yet but i saw it on pocketgear ::obviously:: and it has a utilization screen that might be able to help you out

I rarely soft reset my x50v.

I just did it and went straight to the memory screen. it was almost exactly (or maybe it was exactly?) what it was before the reset.

Here's the result: I think it was Tengo keyboard that was sucking memory at an alarming rate, but with a twist. Only when I used tweaks2k2 to set it as the default keyboard, did that happen. I uninstalled tengo, the problem went away. I put it back on, the problem did not happen. I went to t2k2 and set it as default, and bingo- memory leaking like crazy. So I don't know if this is a problem with tengo or with tweaks2k2.

Thanks to those who looked and wrote or thought about it. Experience goes a long way.

i am seeing something different...

When I first turn on my X50V, and do a soft reset, it shows 11.95mb in use. It stays there steady if I just let it go and watch it.

Now, if I open a few programs, say IE, calculator, word...then close them all using the running programs tab, stop them all...the in use only returns to 12.34mb. If I open say excel and windows media player and close them under running programs, the inuse only drops to 12.41mb. If I continue to open other apps, the in use continues to grow.

If I power the unit off and back on, the inuse is at 12.41. Only a soft reset return it to 11.95mb.

Definately seems like a memory leak when closing apps.

Any ideas or comments?

That's normal. In theory you can make it crash by opening and closing contacts often enough. You should expect some leakage.

why is it normal... does not seem right to have leaks like that.

In theory, shouldnt the memory be freed upon closing the app? Why would a leak be normal?

This would mean that a soft reset would be mandatory after a period of uses.

That's the way it works :) I wish I had a better explanation but whether it's Windows XP, Win2k, or Windows Mobile I expect memory leaks. That's why I reboot on a regular basis and soft reset on a regular basis.

When you open and use programs - e.g. Pocket IE,
they do put some files into the main memory - e.g. IE cache,
so even if you close them, these cache files are not cleared
and take up memory space. That is to say, it's not really
a case of "memory leak". You can just clear off the cache
files from the program menu if it allows - e.g. IE options menu.

wouldnt that be storage memory in use... I am refering to Program memory in use.

It just seems very wrong to have such a constant and reproducable memory leak... I can understand and tolerate casual leaks but ones that drain every time an app is launched?!?!

Microsoft's OSes are full of bugs and security problems, so you can expect problems. If it becomes a big enough problem then Microsoft will issue a fix otherwise you get to wait for a new OS upgrade, which may fix the problem. On a PPC device that usually means a new device. OS upgrades come with a new set of bugs and problems, a never ending circle with Microsoft.

Soft reset recovers the leaked memory. Don't sweat it. Soft reset is the PPC equivalent of Ctrl-Alt-Del and we all know how often THAT combo is used...

Bottom line: M$ writes buggy software.

Sometimes you can get a bad program. With mine EVERY time I run Audio Reader from Audio.com, my memory gets less. I can use Memory Maid and see 5 or 6 of the Reader programs running, and even though I click on the "Terminate" button, they will not close. All I can do is after several times of using the program is to do a soft reboot and they go away and the memory comes back. I have contacted them, but have not gotten an answer yet.

Amen. Bring on Linux for the x50v! Actually, that's slightly unfair...Win2k was a huge leap forwards and my g/f's machine has been running for about 12 months now without a reboot. Quite amazing. My own XP machine runs for weeks without a reboot too. Of course, my Linux box is better again but, MS is getting better. :)
