Application hangup without messages

[Nino Garbin <ni...@gmx.de>]

dear pros,

i have a anoying problem with an application using  the actual struts on 
tomcat 4.1.27 getting data from an mysql-db.

my application works fine doing several requests to call some actions.
the application is framed (navigation, content), each frame calls his own 
action.

at no special point, the application hangs up while calling an action, that 
was called and worked fine before. a look on the heapsize doesn`t
show any suspicious changes. the "hangup" doesn`t seems to depend on the 
heapsize. the webserver is still ok at this moment, other applications 
still work fine. only if i call an action of the current application, the 
constructor of this action is called and after this nothing seems to 
happen.

no error message in any logfile, nothing. only a blank screen.

has anyone an idea? is it probably a connection-problem with the db?
or do you know about similar problems in other projects?

thank you very much for help,

nino
