I was using Cpanel to park a domain and I was getting the following error message:

Error from park wrapper: Using nameservers with the following IPs: xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx. Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver.

The new domain that I want to park is indeed using remote nameservers, and I would like to keep it that way, so solution #1 isn’t ideal.

The other solution isn’t ideal either – I don’t want to make system-wide changes for a single cpanel account.

My solution: I didn’t find this solution listed anywhere else in the forums, but to me, it seems to be the best – simple use WHM to park the domain, or, if you don’t have root access, ask your administrator to do the same. The root user is permitted to park domains that use remote nameservers.

No adding to /etc/ips.remotedns necessary, and you can still keep using remote DNS servers.

Problem solved.

Getting this Linux error message?

Resource temporarily unavailable

It’s because your system is limiting the number of files / processes / CPU that your particular user ID can use.

If you use WHM/Cpanel, enabling the “Shell fork bomb protection” can make the “Resource temporarily unavailable” message appear more often.

Don’t disable the shell fork bomb protection – it’s a good thing. After all, do you want any jackass user to be able to write a perl script containing the line “while (fork());” and bring your system to its knees?

Instead, consider raising the limits for individual trusted users using ulimit. (You will need root access to do this.)

Make the following changes in the system shell init files.

(these files)
/etc/profile
/etc/bashrc
/etc/profile.d/limits.sh

if [ "$LIMITUSER" = "root" ]; then
ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null
elif [ "$LIMITUSER" = "YOUR USER NAME" ]; then
ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null
else
ulimit -n 100 -u 20 -m 200000 -d 200000 -s 8192 -c 200000 -v 200000 2>/dev/null
fi
