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.
