Adaguc-server: Issue with createtiles: closing cdfobject prematurely causes memory violation

[maartenplieger]

When creating tiles, a memory violation occurs because we are clearing a cdfObject which is still used in another place.

See adagucserverEC/CCreateTiles.cpp, 513:

/* Remove the datasource from the cache we just wrote  */
// TODO: Removing this cdfobject causes memory violations. Checkout in issue https://github.com/KNMI/adaguc-server/issues/289
// CDFObjectStore::getCDFObjectStore()->deleteCDFObject(fileNameToWrite.c_str());
