When saving my 90KB text in a LONGTEXT field (using phpmyadmin), nothing happens. Anything above around 64KB doesn't seem to get saved.
I tried to reproduce the same behavior on another server but there it worked, so some setting on my server must be preventing it from saving packets above the 64KB threshold.
Nothing seems to be wrong in the MySQL config file:
key_buffer = 16M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 8
Any idea what the issue could be?
