When submitting a page node: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.

Try the dev coming out in the next 2 hours; let me know if that fixes this issue.

I guess you can call that progress... error every time now! eek.

disable "Asynchronous Operation: output HTML, close connection, then store static file." and try again

"Boost settings for views"
Disable the first 3 checkboxes and try again; if that doesn't work then disable checkboxes "Boost cache expiration/flush settings"
Once we know what causes the issue its easier to fix it

Views are the issue then?

Could you go through the list of view and disable each one (on boost admin side); once you find the view that bombs could you take a peak at the view and let me know if there is something odd about that view?

Same issue for me.
I've the same error while I create a node. The error appeared for the first time when I created one particular view that involved nodes of a particular content type and other nodes with a node reference with the first content type.
This is the export of the view:

$view = new view;
$view->name = 'calendario_casa';
$view->description = 'Calendario casa';
$view->tag = 'Calendario casa';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Predefinite', 'default');

I verified the problem: was related to a computed field, maybe the issue was not related with boost. Removing this field fixed the problem.
