Sounds like a storage engine limit.  In some implementations, myISAM and others, there are limits on the total row size.

What settings can affect limit on size of post? On one installation, I can't
save posts larger than 64KB (around 10 000 words by lorem ipsum generator).
When larger posts are submitted, nothing is saved.

post_max_size is 30M and post_content field is LONGTEXT so that shouldn't be
a problem.
