Hi,
I have a smart device application that saves wav files in a table of SQL Compact Edition database and syncs them back in a SQL Server 2008 R2 database. The type of the field is IMAGE. When the wav file is 2 minutes, data are not be synced and OutOfMemoryException
occurs.As I decrease the size of the wav gradually, until 1 minute, the wav file is synced to the database but OutOfMemoryException occurs right afterwards. Sometimes I also get the exception message:
The buffer manager failed to allocate a buffer of .... bytes but data are not be synced in the database. The
maxReceivedMessageSize and maxBufferSize of my WCF Service are set to 50000000 and I use GZipEncoder for compression. If I drop the sdf and download all data from the server, the sync process completes succesfully.
Below are both stack traces:
