Cpanel Package creation problem : Attempt to free unreferenced scalar

while creating packages for the reseller via reseller WHM we were getting blank page and it appears that the packages were not getting created. After looking into the CPanel error logs in /usr/local/cpanel/logs/error_log the following error was reported.

(internal warning while parsing [stdin]) Wed Aug 193 13:21:08 2009 [94568] warn: Attempt to free unreferenced scalar.

Solution

WHM -> Server Configuration -> Tweak Settings Choose the setting for:

The maximum memory a cPanel process can use before it is killed off (in megabytes). Values less than 128 megabytes can not be specified. A value of “0″ will disable the memory limits.

The settings had 256M there by default, and increasing the value to 1024 MB helped.  The server Server had 4G RAM, so the value of 1024M was fine here.

edquota: Cannot set quota for user 553 from kernel on /dev/vzfs: No such process
edquota: Can’t write quota for 553 on /dev/vzfs: No such process

Solution.

You just need to raise the quotagidlimit from the resource tab on the hardware node. If you do not have access to the Node ask your provider to raise the limit for you.
