Component not working properly after upgrade to 1.5.15 - Joomla! Forum - community, help and support

hi,

i've got big problem after upgrading joomla on website 1.5.7 1.5.15.
my site uses custom developed components, modules, plugins , templates everything, , until upgrade, worked flawlessly.

now still work except 1 instance. when try display page lot of data (at least 1000 records database, formatted html links other pages), pages don't display @ all.

it seems type of output buffering , memory limits have been implemented prevent page displaying if page ends being large, because if place <?php exit (); ?> @ end of view component, see output, albeit without surrounding site template.

has there been changes between 1.5.7 , 1.5.15 might have triggered this? seems memory related me, don't know sure.

any appreciated!

thanks

i've done more testing , found upgrading 1.5.7 1.5.9 works fine. higher not work , triggers blank page on data.

anyone have idea changed between 1.5.9 , 1.5.10 might causing this?
