# ERR_MISC_EOPENF: Too many open files¶

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

## Remediation¶

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.
