What you might try is to create a filter that takes all incoming data on the tcp socket, replaces ^M with \n, and then pipes it back into another source driver (socket, pipe, whatever) for syslog-ng to process again, but without the filter expression (^M is probably \r as thats what most editors will display \r as).
I'm not sure if that'll work, but I think it should.

Subject: Re: [syslog-ng] Multiple syslog messages in one tcp packet 
I’ve got a Windows syslog client (from Q1 Labs) that wants to send multiple syslog messages within a single tcp packet to syslog-ng. The messages file on the syslog-ng side looks like this (Note the “^M<13>” separating the individual messages):

[user] [notice] Oct 11 16:25:05 10.40.3.16 10.40.3.16 ation_logfile.txt Payload=server.Emory.Edu, The Operations Manager agent processes are using too much processor time SEVERITY:2 STATE: New; Custom Oct 11 15:15:58^M<13>Oct 11 15:17:58 server2.emory.edu AgentDevice=FileForwarder        AgentLogFile=logfile.txt    Payload=Microsoft.SystemCenter.AgentWatchersGroup, Health Service Heartbeat Failure SEVERITY:2 STATE: New; StateCollection Oct 11 15:17:58^M<13>Oct 11 15:19:58 server2.emory.edu AgentDevice=FileForwarder        AgentLogFile= logfile.txt    Payload=Microsoft.SystemCenter.AgentWatchersGroup, Health Service Heartbeat Failure SEVERITY:2 STATE: Closed; StateCollection Oct 11 15:19:58^M

Is it possible to configure syslog-ng to separate the messages out into individual ones like these?

[user] [notice] Oct 11 16:25:05 10.40.3.16 10.40.3.16 ation_logfile.txt Payload=server.Emory.Edu, The Operations Manager agent processes are using too much processor time SEVERITY:2 STATE: New; Custom Oct 11 15:15:58
[user] [notice] Oct 11 15:17:58 server2.emory.edu AgentDevice=FileForwarder        AgentLogFile=logfile.txt    Payload=Microsoft.SystemCenter.AgentWatchersGroup, Health Service Heartbeat Failure SEVERITY:2 STATE: New; StateCollection Oct 11 15:17:58
[user] [notice] Oct 11 15:19:58 server2.emory.edu AgentDevice=FileForwarder        AgentLogFile= logfile.txt    Payload=Microsoft.SystemCenter.AgentWatchersGroup, Health Service Heartbeat Failure SEVERITY:2 STATE: Closed; StateCollection Oct 11 15:19:58

I am using the syslog-ng ose client version 3.0.3.

Thanks.
