  1. foundin changed to: "1.0.112"
  2. icomment:
    We intermittently experience an AccessViolationException while acessing an open reader in our .NET Core 3.1 based windows service.
    Basically we use a single shared SQLite connction accross many TPL Dataflow tasks which works fine. The database is operated in WAL mode and the serialized isolation mode is implicitly used. However, after several hours of operation and millions of data rows written into the database an access violation occurs in SQLite.Interop.dll.
    
    Unhandled exception at 0x00007FF8CCC54618 (SQLite.Interop.dll) in Service__PID__4772__Date__06_29_2020__Time_02_42_55PM__613__First Chance Access Violation.dmp: 0xC0000005: Access violation reading location 0x0000000000000011. occurred

    Since still unable to reproduce this error in an isolated environment I only can provide a scarse amount of information.
    Any help would be highly appreciated.
