In reply to Ravi Saive. Thank you, We are Using RHEL 6. Checked the /etc/limits. d/90-nproc.conf this file has same values as you mentioned. However when I run ulimit - u as root or any other user get value 150. In file /etc/security/limits.conf file I commented line * hard nproc 150 which was there before. I logged out restarted httpd still same value is coming. How reset default nproc value for root and other users. Please help

In reply to Deepa. @Deepa, The system wide configuration file /etc/security/limits.d/90-nproc.conf (RHEL6) and /etc/security/limits.d/20-nproc.conf (RHEL7) specifies the default nproc limits as:

*            soft    nproc     1024
root       soft    nproc     unlimited

I am able to change the nproc for additional users using /etc/security/limits.conf but some how root users nproc value set is 150. When logged as root and execute ulimit -n I get the value 150. How can I change root users nproc value?
