The forum becomes non-usable when it cannot display the contents of a post.
It seems this bug is affects advanced forum too where when there are many unicode words node shows up as just blank.

vm commentedit affects advanced forum too, because advanced forum builds off of the core forum.module.
This isn't something to be solved by or in advanced forum.
I'll let michelle mark status though.

michelleYou've clearly demonstrated that this isn't a bug in AF since drupal.org doesn't use AF. If it's fixed in core, AF will be fixed as well. It would help if you'd link to the issue you filed for tracking.

kaakuu commentedThanks - the only problem is that I find it to be happening with much less number of words ( approx 15,000) than reported in the above link. But I will wait for other reports that may drop in here in the future from users or sites that actually uses long posts and fails.
Closing this for AF.
