Connection was Reset preventing edits etc

I have been having a problem for a few months which effectively means I only get one shot at creating a new form on any of my websites. Whenever I try to update a form, or import a previously exported form, I get
"The connection was reset

The connection to the server was reset while the page was loading."

Any suggetions as to what might be causing this to happen would be greatly appreciated.
It even happened on a brand new installation of wordpress where gravity forms was the only installed plugin. (I am using Genesis Framework too).

I have looked at error logs but nothing was there. My hosts are called catalyst2, who are very helpful, could you suggest what I should be asking them?

Yes - I keep hoping that an update will fix the problem, but no luck.

Will try the memory thing and let you know, thanks

Am using 38M out of 128 available (both WP and PHP) So guessing that's not the problem?

Can you send a WP admin login and reference this post to rob@rocketgenius.com

Got it - can you 100% confirm for me that you have run through the instructions that we have here for checking for plugin/theme conflicts.

Well, I just talked with one of our developers and showed him what was going on. The consensus was this was out of our league to try to troubleshoot and that you should contact your host/server as they will have better tools and logs to help you try to figure out what's going on.

You can set WP_DEBUG=true in your wp-config.php and see if you get an actual error to send them. Otherwise, just send them the link to the page and tell them what is happening.

At the moment I seem to be caught in the middle somewhat, as they can't see anything which gives them any indication of what might be the problem.

Thanks Alex, I appreciate that. I have sent details as you suggested
