guys, so i'm running build 21018 cooked with kitchen rev C2 for almost a week now and all is well except for some intermittent exchange server problem (basically wouldn't push the mails) and a mysterious memory leak problem.

the culprit seemed to be the "activesync fast data synchronization" option under "settings" -> "connections" -> "usb to pc". after unchecking it and rebooting, i was able to reclaim 15MB of ram! and the exchange server decided to behave again.

just want to put it out there to see if anyone understood why...

You should PM Bob aka oldman.

What makes you think that I would know the answer? I'm just a wise-@ss engineer. I don't even use an Exchange Server. But interesting discussion going on because 1 suggested technique to keep ActiveSync from always coming on is to create a "dummy" server, and set the scheduling to Manual. Wonder how doing that would tie into this discussion about memory leaks.

I have seen memory leak too, about 10MB/day: I'm trying your suggestion out to see if the leak goes away and will report back if it seems solved.

yep buddy. i'm running the build you uploaded heh. 10mb is about the size of the leak.

i just realized unchecking "faster data sync" means switching back to the old direct usb connection with activesync...

I'm not sure what maybe causing the memory leak... if it is in fact a memory leak.

I am running 21018 sys with a few things stripped out, and former's XIP... i haven't rebooted in 3 days? my memory usage is at 58%. IF you think you have a leak, use cleanRAM rather than resetting all the time. It will wipe all the processes that are not responding... and will often save you 10mb or more.

memory is also allocated for applications as they are loaded and does not always free up when the program stops using allocated resource... Perfect example on TF3D...

Load manila and look at your free memory... go through each tabs, now your free mem is decreased subtancially. you will never get that memory back unless manila is restarted, or... you reset your phone, or a memory reclaiming tool is ran.

I'm now testing w/o TF3D-- bloatware at it's best-- and seems steady at around 62MB down from 63MB after loading a few apps and clearing w/TM. I have HTC GPS Tool running in background too. I use MemMaid and SKTools for memory management, but will check out cleanRAM to see how that work too.

Really just testing now, but am very happy with this build/ROM; customization begins in earnest tomorrow, and that I'm looking forward to immensely

thanks bud. i tried reclaiming the ram using memmaid but every time only a tiny kilobyte amount was reclaimed--whereas i saw 10mb slipping away in front of my eyes. hmm..
