PGV causing too many open session on host

[Dietmar Kurtz]

I was on my host making many updates, and after a several hours my IP was locked out due to too many open concurrent sessions.  I have contacted the hosting company and they pointed to a possibility of a php not finishing properly.
Has anyone run into a similar problem?

This sort of thing can happen if a script/robot tries to do a scan of your site.  Robots don't send cookies, so each page request acts like a separate login.

PGV does a pretty good job of identifying robots (and avoiding the session-overload).

I'd look in your access logs to see if there is any unusual pattern of access.
