Maximum Concurrent User Tickets Limit Exceeded

Maximum Concurrent User Tickets Limit Exceeded

Hello, I'm relaunching my application a lot during development work and have hit this API login problem after about four months:

"https://accounts.zoho.com/login" with the correct parameters set returns:

"#
#Thu May 19 04:30:10 PDT 2011
CAUSE=Maximum Concurrent User Tickets Limit Exceeded
RESULT=FALSE
"

I can't find any reference to this error. I assume it's because I'm logging in very often. Normally I wouldn't login so often but am relaunching and re-logging in every time during development. Is there any way I can clear the tickets I have? What number of tickets am I allowed?
