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

[Jay Guerette]

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?
