Subject [jira] [Commented] (INFRA-15685) Raise UserTasksMax in systemd
Date Mon, 01 Jan 2018 07:25:00 GMT

    [ https://issues.apache.org/jira/browse/INFRA-15685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16307383#comment-16307383

Gavin commented on INFRA-15685:
-------------------------------

All these nodes are shared between hundreds of projects, there has to be a sensible limit
to what runs on these nodes and I don't think allowing multiple users (and multiple x UserTasksMax/ulimit
etc) is the answer. That sounds almost as bad as increasing the number of executors.

> systemd limits the maximum number of processes (and native Java threads) a user may consume
on a box via UserTasksMax.  This should probably be raised in the case of Jenkins build hosts.
