Error post.

Your error is with MySQL. You are generating too many SQL connections concurrently to the database so its rejecting new ones.

And this happens only when I try to install CereusReporting plugin. Any idee why? Or where to look for issues?

LE: I changed spine poller proc/thread from 5/10 to 1/10 and increased mysql max connection to 500. Seems that did the trick, thank you for the hint netniV. Can be closed.
