We have begun to see errors around too many open files on one of our solrcloud nodes. One replica tries to open >8000 files. This replica tries to startup and then fails the open files are exceeded upon startup as it tries to recover.
Our solrclouds have 12 distinct collections. I would think that the number of open files would depend upon the number of collections as well as numbers of files per index etc... Our current setting is 8192 open files per process. What values are recommended? is there a normal number of open files? What would lead to there being lots of open files? -- This message and any attachment are confidential and may be privileged or otherwise protected from disclosure.
