I have been using MP 1.2 beta since it's launch and having been having the same issue since installing.
Whenever I load the MP Client on the odd occasion I get a windows crash report popup and advise that it needs to close the program, if I ignore the message I can still use MP 1.2 and have not seen any problems from within the program. Once I close MP the message is still there and pressing close obviously does nothing but gets rid of the message.

I have attached my logs for you to have a look through and see what the issue may be.

I have a few plugins installed and have tried disabling these one by one and I still get the error. I thought it may be linked to my music but can't see any reason for this.

Hope someone can help

Let me know if you need any more info.

Cheers

Phil

Hi,

It looks as though the critical part is

2011-05-28 17:05:46.451700 [ERROR][MPMain(1)]: Exception   :Error: DatabaseUnavailableUnclassified
Gentle.Common.GentleException: The database backend (provider MySQL) could not be reached.
Check the connection string: Server=PhilBath-HTPC;Database=MpTvDb;User ID=root;Password=***;charset=utf8;Connection Timeout=300; ---> MySql.Data.MySqlClient.MySqlException: Reading from the stream has failed. ---> System.IO.IOException: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine
   at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)

This would suggest that MediaPortal cannot connect to the TV server.

Is this a single seat or multiseat install? I see from this that the password in gentle.config is not the default one. Did you just install MySQL to use with MediaPortal, or did you already have it installed for another reason?

Earlier in your logs there is another error:

2011-05-28 17:05:31.229830 [Info.][(9)]: Exception   :System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

and you have a massive amount of logging for things like

I would try turning off the 'file existence cache' feature (I assume you have it enabled) and see if this helps.

Hi Mark,

Thanks for looking into this for me.
It is a single Seat install, although I have set it up so that other clients can connect to this one (at some point would like to have MP on another PC).
I have made two changes one is entering the fixed IP address rather than the Computer name in MP client config (not sure if that makes a huge diff or not) and also turned off the file existence cache feature.

MySQL was installed initially for MP 1.1.2 and has been on ever since. I have upgraded to 1.2.0 from 1.1.3 (if that changes anything)
Having looked at the gentle.config the password held is the same as the default one.

I will see if the error happens again (2 restarts and 6 loads today since the changes noted above and no error) and then will post back.

Cheers

Phil

Hi Mark,

After another few days testing I can safely say that the crash has not come back.

Many Thanks
