Memory leak in latest build (1 Viewer)

[Raven]

Has anyone else noticed a huge memory leak in the latest build?
When I woke up this morning Media Portal was using 758 MB of RAM and had consumed 1 hour and 15 minutes of CPU time since 3 AM this morning.

I noticed it also it's in todays and yesterday cvs build. I sitch back to acvs from a week ago (just had that one on my harddrive)
After startup today my system was running out of memory and task manager showed mp with 800MB+.

Same problem here..... switching back to older CVS.....
running out of memory LOL

I think I may have found what caused the problem on my system at least. I deleted the task for updating the tv guide and now MP doesn't seem to leak memory anymore.

Hi,

I'm experiencing the exact same thing. It seems that while updating the tvguide (with WebEPG in my case) MP gets into a race condition. Some extracts from the log:

7-1-2006 6:55:01 WebEPG: TimeZone Not valid
7-1-2006 7:16:07 SQL:TVDatabaseV21.db3 cmd:sqlite3_step err:ERROR detailed:database schema has changed query:select * from channel,tblPrograms,genre where genre.idGenre=tblPrograms.idGenre and tblPrograms.idChannel=channel.idChannel and channel.strChannel like 'NET5'  and ( (tblPrograms.iEndTime>='20060105071600' and tblPrograms.iEndTime <='20060109071600')  or (tblPrograms.iStartTime>='20060105071600' and tblPrograms.iStartTime <= '20060109071600' )  or (tblPrograms.iStartTime<='20060105071600' and tblPrograms.iEndTime >= '20060109071600') ) order by iStartTime

It seems the message "database schema has changed" is the key, since it's repeated a few times after this. After a little while, the error.log shows:

7-1-2006 7:29:29 SQL:TVDatabaseV21.db3 cmd:sqlite3_step err:ERROR detailed:SQL logic error or missing database query:vacuum

and eventually a:

7-1-2006 7:57:34 TVDatabase exception err:Exception of type 'System.OutOfMemoryException' was thrown. stack:   at System.Collections.Generic.List`1.set_Capacity(Int32 value)

Today I began with a clean TVDatabase, to see if corruption of the database might be causing this. We'll see tomorrow. I do however think that this error is caused because some objects in the database have been changed/updated while the tvguide is being updated. Maybe a (multi)threading issue?

EDIT: All this with CVS version mediaportal-cvs-01-06-2006--01-04

Kind regards,
Michel

OK,

It looks like MediaPortal lived through the night
No "OutOfMemoryException", "SQL logic error or missing datbase query" anymore in the error.log. But, I still see the "database schema has changed" errors:

(please ignore the WebEPG "grabber error" for ChannelId: ned3@omroep.nl, it's known to me and something I need to fix )
So far it seems that at least the race condition is gone since I've recreated the TVDatabase.

Kind regards,
Michel

Hi !

Is this problem solved already in the latest builds ? I don´t see anything in the changelog ....

Thanks,
Alex

 

[5teve]

guys a bit off topic but are you all running VMR7? i think i remember a memory leak occuring with vmr7 (overlay) enabled... if so change to vmr9 and see if that helps

Thanks

Steve

 

[midiboy]

Hi !

No, I am using VMR9 already. also this leak occurs with no video playing ...

 

[KRA]

Any news on this? I still have this problem with yesterdays build.

Everything was fine, then memory usage startet raising, from the normal 130mb, and already at 200mb mediaportal startet skipping sound/video, a little later mediaportal was not responding. I've seen it using 7-800MB before then I killed the process.
