Assigning to Tony who should decide whether it is fixable. (we might open the files one by one and copy them to memory?)</p> <p>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 <img class="emoticon" src="https://jira.opendaylight.org/images/icons/emoticons/sad.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Filesystem caching adapter, should cache schemacontext / parsed ANTLR YANGContext<br/> to minimize number of reads from filesystem for same YANG models.</p> <p>Fixed with InMemorySchemaSourceCache.</p> Development External issue ID 658 External issue URL Rank 0|i02jdj:
