NSCA recive plugin output more than 4kB


I’ve got another problem with Nagios. Finally after few tweaks I can send from client and receive on my server host HTML formatted output data. But now there is another problem. When i look t my log i can see that sometimes I receive whole message from my client plugin output (more than 4K:roll:, and sometimes is exactly equal 4096 bytes. Any suggestion?

Best Regards
