It seams that my MediaPortal 0.2.2 has memory leak and I would like to know does any one out there has same experience. I'm not posting logs right now because first I would like to know is this my system specific issue. Well, how to reproduce this problem? Actually quite easy… my MP 0.2.2 allocates about 10-20MB every time it constructs directshow graph, but when graph is destroyed memory is not released. So every play-stop of recorded TV show and every background recording (yes, not only graphs are rendered to screen have this problem) adds 10-20MB to MP's footprint and it easily grows to over 800MB. Since this is quite obvious memory leak I suppose that it is something about my .net or directx and not MP, so I would like to ask you to check with your MP 0.2.2 installations.
I don't use TV server, and I'm using MPV/MPA codecs but I think it is not codec specific problem because recording graphs don't use codecs…

thx

Try deleting the TV cards and deleting the database as well. I've had this a couple of times when i've changed versions and been playing around.

I don't know what causes it, but that seems to fix it.

well, you may be right... i found something interesting... first, every entry to recorded tv allocates about 15MB and never returns it... than every playing of show from recorded tv gets another 10-20MB... so, maybe it is not problem with DX wich I previously suspected... maybe it is database problem... but I deleted all databases (from database directory) and let MP create new ones... unfortunatly didn't help... this behaviour is observed on 3 different systems... so... maybe it is problem in MP... any new observations or suggestions are more than welcome.

EDIT 1: After long investigation it seems that problem is in generating thumbs for recorded shows... if MP founds recorded shows without thumb in thumbs\tv\recorded directory it tries to generate one using DvrMsImageGrabber... since no thumb is generated and memory isn't released i supose that DvrMsImageGrabber hangs... so... does anybody know how to stop MP traying to generate thumbs for recorded shows or what is possible reason for this behaviour of DvrMsImageGrabber
