[syslog-ng]Log line lost during TCP connection?

I have a postfix server logging via syslog-ng. The log data is written to a local file and also sent via TCP to a central syslog-ng loghost. On the source server (syslog-ng 1.6.6 on Linux) I see: 05:32:21 internal/smtpd[15534]: 9AE172D29A5: client=x.x.net[10.x.x.x] 05:32:21 internal/qmgr[9993]: 9AE172D29A5: from=<x@x.com>, size=1557811, nrcpt=1 (queue active) On the central loghost (syslog-ng 1.6.5 on Linux) I see: 05:32:21 syslog-ng[28919]: AF_INET client connected from 10.x.x.x, port 33645 and 05:32:21 internal/qmgr[9993]: 9AE172D29A5: from=<x@x.com>, size=1557811, nrcpt=1 (queue active) The 1st line from the source server is missing on the central loghost. Is this a bug?
