Can you try logging the [HTTP::request] value to get the full HTTP request headers. If it's over 1k bytes, you might want to log it remotely using HSL as logging locally via syslog-ng is limited to ~1k bytes.

As Steve said, it might be that you're dropping these requests with this or another iRule. That might trigger this runtime error.
