Subject Re: Ulimit on machines

David,

Ulimits are set on process startup. I think Jenkins slaves are started via
ssh, if PAM is used, pam_limits would set them based on
/etc/security/limits.conf. Host reboot is not required. For child process
should inherit parent by default.

Looking at sshd_config, UsePAM is no

Updated /etc/ssh/sshd_config and restarted sshd. Once jenkins slave
process are restarted they should get new limits.

Thanks
