UDP Datagram LB

    hello,

    FYI, I solved this problem with a simple stateless VS: K13675

    Thank you all

UDP datagram LB forwards traffic packet-by-packet, and no loger treats UDP packets from the same source and port as part of a connection, so if syslog message is split into multiple packets you might have part of the log on one server and part of the log on the other one, possibly resulting in messages missing.
