Description
Monolog version 2.9.1 in a Laravel 9 environment on Ubuntu 22.
I use the SyslogUdpHandler to send logs via Syslog to third-party systems.
It works, but when the log message is longer, then it gets truncated. What can be the reason for this, and is there a way to not have it truncated?
If I log the message just before the socket_sendto($this->getSocket(), $chunk, strlen($chunk), $flags = 0, $this->ip, $this->port); call in UdpSocket.php, then I still see the correct length.
However, if I monitor it with tcdump, what I see is a single packet and that the message is truncated when it gets sent over:

Since the actual log message is a JSON, it can't be parsed on the receiver if it's not complete.
