Server error in fetching remote contact RRS feed

  • Question

  • Hello,

    we frequenlty synchronise data from an android application to an sql server 2008 r2. We are using sync framework 2.1 and it was working  until this morning where an unexpected  arrived (she doesn't occure systematicaly but very often ) 

    Server error in fetching remote contact: HTTP/1.1 500 Internal Server Error 
    {"ErrorDescription":"Microsoft.Synchronization.Data.DbSyncException\u000d\u000a Cannot enumerate changes at the RelationalSyncProvider for table 'Table Name'

    and then:

    Expiration Timeout

    we already increase the timeout to 30 min. we don't have any clue of what going on.

    Thanks for your help,
