I am increasing nproc limit for one of a development user account in my rhel6 system . After searching some rubust solution , I zerod at editing /etc/security/limits.conf with these two lines :
@dev_user hard nproc 4096
@dev_user soft nproc 4096
For some cases I have to deal with so much number of threads that's why I want those numbers high . Also this solution serves the pupose well . BUT my problem is if any time I edit that file with sudo permission then it only becomes after the system restart.
This dev_user have been provided root access with sudo permissions only. Here is my humble request to you to please suggest me some solution which should do the task without restart . Also increased limits should last long until unless no else edits it again.

The settings specified in
/etc/security/limits.confare applied bypam_limits.so(man 8 pam_limits).The pam stack is only involved during the creation of a new session (login). Thus you need to log out and back in for the settings to take effect.
