Installing git on cPanel server gave a strange missing RPMs error though the rpm was existing in the CentOS 6 repo.
Error: Package: git-1.7.1-3.el6_4.1.x86_64 (base)
Requires: perl-Git = 1.7.1-3.el6_4.1
cPanel is known to create these issues as it won’t allow many of the RPMs to be installed and it also excludes major software RPM’s in yum configuration files.
To get rid of the error related to git I had to forcefully disable the main excludes as follows:
yum install git –disableexcludes=main
This indeed resolved the problem.

To limit tomcat heap memory usage we normally change the environment variables in tomcat startup scripts. cPanel allows us to take care of this by creating and adding min and max values to a file called /var/cpanel/tomcat.options (File won’t exist by default).
-Xmx200M
-Xms100M
the “-Xms” initial Java heap size for the application to 100MB, and the “-Xmx” maximum Java heap size to 200MB. If the – is not placed in front of the option when putting the values into /var/cpanel/tomcat.options file that is created, then Tomcat will refuse to startup properly.
This method would be preferred over directly editing /usr/sbin/starttomcat. The /var/cpanel/tomcat.options file would not be edited by cPanel scripts or upon updates.

If you’re running cPanel server on a OpenVZ hardware node, you might face issues with quota for few reasons:
1. Secondary quota might not have been enabled on hardware node.
You can verify by checking for “DISK_QUOTA=yes” in /etc/vz/conf/vz.conf
Also, QUOTAUGIDLIMIT needs to be set for the VPS in /etc/sysconfig/vz-scripts/CT_ID.conf (PS: CT_ID is the container id of the VPS)
2. You should have initialized the quota via WHM.
If you continue to face problem even after applying both fixes, re-initializing quota might help as per https://wiki.openvz.org/Cpanel_quotas Here is the excerpt:
WHM/Cpanel, a popular commercial web-based control panel for Linux, has a tendency to overwrite the special quota files in the VE context. I am referring to:
lrwxr-xr-x 1 root root 39 Jun 8 17:27 aquota.group -> /proc/vz/vzaquota/00000073/aquota.group
lrwxr-xr-x 1 root root 38 Jun 8 17:27 aquota.user -> /proc/vz/vzaquota/00000073/aquota.user
The result of these being overwritten will be WHM showing “unlimited” quota reports for all users in the system. An quick solution to this is to run these commands from within the VE as root:
rm -rf /aquota.user 2>/dev/null
rm -rf /aquota.group 2>/dev/null
unlink /aquota.user 2>/dev/null
unlink /aquota.group 2>/dev/null
for x in `find /proc/vz/vzaquota/ | tail -2 `; do ln -s $x / ; done
journled quota support warning didn’t get resolved even after this. Yet to check for the core reason for the same.
