Could you please give some more information about your scenario so that we could try to reproduce the issue:
- are you using windowless mode ?
- are you showing external pages
or HTML strings
- do you open and close/remove them from the visual tree the Placeholders frequently ?
- how do you unload the Placeholders ?
There's a known memory leak issue
with the HtmlPlaceholder and maybe your scenario is the same but we'll need more information in order to confirm this so any code snippets or additional elaboration will be appreciated.
We're looking forward to hearing from you again.
