Process Limit Adjustment.md

Problem Statement

In the Stratos Datacenter, our Storage server is encountering performance degradation due to excessive processes held by the nfsuser user. To mitigate this issue, we need to enforce limitations on its maximum processes. Please set the maximum process limits as specified below:

a. Set the soft limit to 1025

b. Set the hard limit to 2026

Solution

---

1. Connect to the Server

1. SSH into the Server:

   ssh natasha@ststor01

2. Switch to Root User:

   sudo su

2. Verify the nfsuser User

1. Check the nfsuser ID:

   id nfsuser

3. Configure Process Limits

1. Edit the Limits Configuration File:

   vi /etc/security/limits.conf

2. Add or Modify Limits for nfsuser:

   • Add the following lines to set the soft and hard limits for the nfsuser:

     #@student        -       maxlogins       4
     nfsuser          soft    nproc           1025
     nfsuser          hard    nproc           2026
     

4. Verify the Changes
