WordPress database error MySQL server has gone away for query

My hosting has shut down our website because of following error:

WordPress database error MySQL server has gone away for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES (‘_transient__simple-calendar_feed_id_????_google’, ‘????’)

(I replace some id and the value with ????)

I think our value is just too big for mysql to handle.
The value looks like all items on our calendar.
I assume that this value is way too big to save, as our calendar is an international sport calendar with multiple detailed items almost every day. Why would you want to save this into the wordpress database?

We only have this problem since the last update. (3.1.0)
