is there limit on domain length

Hi,
I have my cwp all installed and have a few domains on it already and working fine , today i tried to add a domain and it kept throwing error..
Changing password for user *****.
passwd: all authentication tokens updated successfully.
Changing shell for *****.
Shell changed.

Warning! User Account ***** not added !!!

I can still add users as i tested another afterwards , only thing i can notice is that this is longer then other domain names , is there a length , or where can i see error log for this ?
I did try to  userdel -r *****    and try again but same result.
Length may be no issue but i could see nothing else obvious to cause it , any help greatly appreciiated.

You can tail cwp logs from shell console when creating new domain, looks strange how long is this domain ?

tail -f /usr/local/cwpsrv/logs/*log
