| Description |

on startup in our lab OpenDaylight peaks at 1370 file descriptors in use before settling down to around 600. we have four routers with NETCONF/YANG plus BGP-LS from one of them to the controller. is this expected behaviour? |

The problem seems to be caused by large number of yang files downloaded from the router. Assigning to Tony who should decide whether it is fixable. (we might open the files one by one and copy them to memory?) |

makes sense. Or is there a way to open each file once only? If you're connecting to a number of identical routers then you'll be opening the same set of files multiple times. In an SP-sized network that could even take you past 64K file descriptors |

Filesystem caching adapter, should cache schemacontext / parsed ANTLR YANGContext |

Fixed with InMemorySchemaSourceCache. |
