Hi all,

I have a problem with my Zope, he hangs unexpectly if i view a special
Method which generates Diagrams with data from a PostgresDB.
The data are selected by a timespan( default is 24 Hours ).
The Method works as descripted bellow:

First when i call foo, then the HTML-Code is rendered with some
images-tags, which are generated by selects.
The image tags are calling the method foo which returns image data.

If i want my diagrams from 2001-06-01 5:00 to 2001-06-01 12:05
everything works fine.
If i want my diagrams from 2001-06-01 5:00 to 2001-06-01 12:10 Zope
hangs, no exception no log entry, Zope only hangs.
If i want my diagrams from 2001-06-01 5:05 to 2001-06-01 12:10 which is
the same timespan as example 1 Zope hangs too, no exception no log
entry, Zope only hangs.

If i view the postgres logs the nothing happens.

Could anyone help me to find the problem or the place Zope is hanging

thanks as

P.S.: Exact the same problem occurs when i you another PostgresDA ????
