# ERR\_MISC\_EOPENF: Too many open files[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_MISC_EOPENF.html#err-misc-eopenf-too-many-open-files "Permalink to this headline")

DSS and its subprocesses hold more open file descriptors than the limit configured for this system/process/user.

## Remediation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_MISC_EOPENF.html#remediation "Permalink to this headline")

This issue can only be fixed by a DSS administrator.

To fix this issue:

* Stop DSS, and make sure no processes are still running

* Check the allowed number of open files with `ulimit -n` (as the unix user that runs dss)

* Increase that limit, ideally to 64,000

* Restart DSS

If this does not solve your issue, please report the issue to Dataiku support.
