Could not connect: User boot7com_hoston has already more than 'max_user_connections' active connections

I was the only one at the site and all I did was upload a video. It happens after uploading a video...right after it reaches 100% on the upload then WHAM, get that error. I've gotten this error on at least 3 occasions. Doesn't always happen, but it has happened more often than I am comfortable with.

Here is what the host had to say:

You should be concerned about this error, it means your site is either A) leaving MySQL connections open & never closing them (thus limiting your access due to future attempts that are denied because you already have the maximum number of connections. Or B) your site is receiving a very large amount of traffic, this could become a problem if the error becomes present more often, your site could begin using more server resources and be subject to action being taken to rectify the situation.

If the error is present a lot of the time but your account is not using near what we consider to be overusage of shared server resources, we may be able to make modifications to the configuration to alleviate the error. For this you would need to send in a support ticket so they can look in to it for you and make a determination.
Admin, where they say A) leaving MySQL connections open & never closing them (thus limiting your access due to future attempts that are denied because you already have the maximum number of connections. Is this something to do with the script?

I did notice, however, that the video was still converted and then appeared on the site like normal but the error is disconcerting, especially to a visitor.

UPDATE: I heard back from my support ticket. They had to fix the max user connections setting on the sql.
