How to increase the quotaugidlimit in a vps

Quotaugidlimit is the number of user/group IDs allowed for VPS internal disk quota.
If you see error message like this trying to manage users’ quotas inside a VE:
edquota: Can’t write quota for 32063 on /dev/vzfs: No such process
Resetting quota for admin2 to 0 Meg….Done
Or if we see WHM cpanel users limit as UNLIMITED or ZERO
then probably  reason is that second-level quota limit is exceeded and user quotas above a limit were not loaded.
Please increase QUOTAUGIDLIMIT parameter value for a VE to the number
which is greater than sum of users and groups created (or supposed to be created) in a VE.
This command will show you current usage of second-level quotas in a VE #101, you may run it on a hardware node:
# wc -l /vz/root/101/etc/{passwd,group}
95 /vz/root/101/etc/passwd
107 /vz/root/101/etc/group
202 total
You may increase QUOTAUGIDLIMIT parameter using ‘vzctl’ utility on a node:
# vzctl set 101 –save –quotaugidlimit 210
To apply changes it is required to restart VE:
# vzctl restart 101

How to check if VPS has problem with its RAM memory

[[email protected]]# less /var/log/messages|grep OOM|grep VEID |wc -l
191
[[email protected]]#

This means that you have hit your RAM (memory) limit “191″ times until now. When you hit the memory limit, the services running in your VPS will get affected and may go down since there is not enough memory for them to run.
