constructor TLoggerProUDPSyslogPacket.Create(pLogItem: TLogItem; pHostName: string; pUserName: string;
pApplication: string; pVersion: string; pProcID: string; pUnixLineBreaks: Boolean; pUTF8BOM: Boolean);

If pUnixLineBreaks is false the logger doesn't sends the LogMessage. Currently:

if FUnixLineBreaks then
FMessageData := pLogItem.LogMessage.Replace(sLineBreak, '#10', [rfReplaceAll]);

Should be:

if FUnixLineBreaks then
FMessageData := pLogItem.LogMessage.Replace(sLineBreak, '#10', [rfReplaceAll])
else
FMessageData := pLogItem.LogMessage;
