We are having a similar problem on one particular server of ours.
We are using WHMCS (
www.whmcs.com) which uses the /xml-api/createacct function to create accounts on the remote cPanel Server.
Creating the account on our server does not work, and on further inspection, WHMCS is definately connecting to the server, and it seems to be going through the process because we can see the domain being created in httpd.conf, etc/passwd, etc/group and more - but it does not seems to finish, and when checking for the domain in cpanel/whm, the domain account it is no where to be seen. It does not show up in 'List Accounts' nor in the DNS zones.
As far as we know, all servers are setup the same, so why this one server is having problem is very strange.
I contacted WHMCS Support and this is their exact response verbatim after they tried to fix the problem:
-----------------------------------------------------
When running the create command, a very unusual thing seems to be occuring and that is the cpanel account create API call terminating without any response. Here is the command sent and response received:
Request: /xml-api/createacct?username=whmcss&password=NLws9QIWe6gY&domain=whmcssupport.com&plan=Plan+Two&savepkg=0&featurelist=default"a=1000&bwlimit=30000&ip=n&cgi=y&frontpage=y&hasshell=n&contactemail=newclient%40domain.com.au&cpmod=x3&maxftp=unlimited&maxsql=unlimited&maxpop=unlimited&maxsub=unlimited&maxpark=5&maxaddon=1&reseller=0&
Data:
This is very unusual not having seen it before so you'll need to contact cPanel to look into it for you. Normally it should always give a success or error message response - never blank.
-----------------------------------------------------
Does anyone have any ideas at all how to solve this?
Really need help on this one
