Hi, If I understand you correctly, you have three client/servers, don't you? client(.218) -> relay server(.198) -> local server on relay server (127.0.0.1) and the problem is that sometimes your relay server drops the connection of client. James Pirman írta:
Is there anyone that can help with this? Is there any more information that I need to provide in order for me to get help? I've been dealing with for weeks and am starting to think the only solution is to write my own server.

I am currently having an issue with syslog-ng 3.0.4 where my TCP connection between my client and server is lost throughout the day. By looking at the pcap file from tcpdump I can tell that the TCP connection reset was initiated by the syslog-ng server. The only information that was initially in the log file regarding this disconnection was the following 2 lines:
<45>1 2010-01-05T10:29:32.323-06:00 server-db-01 syslog-ng 29213 - [meta sequenceId="2733719"] notice Syslog connection closed; fd='9', client='AF_INET(192.168.27.218:46326)', local='AF_INET(192.168.27.198:20514)' Can you show me the previous few lines before this log message? Because if syslog-ng drops the connection usually sends log message about the reason of this behaviour, like this:
2010-01-07T17:24:48+01:00 syslog-ng err Invalid frame header; header='' 2010-01-07T17:24:48+01:00 syslog-ng notice Syslog connection closed; fd='10', client='AF_INET(10.100.20.1:33251)', local='AF_INET(10.30.0.32:20514)' Your client config can also be useful, the problem may be on client side. Can you show me the debug log of your client when the connection lost?
and
<46>1 2010-01-05T10:29:32.323-06:00 server-db-01 syslog-ng 29213 - [meta sequenceId="2733720"] info Closing log transport fd; fd='9'
In order to get more information, I set the following flags in init.d: "-v -d -t".
This did not give me any more information about the TCP disconnect, however I did notice that a lot of my normal messages were preceeded by the following text:
<47>1 2010-01-05T10:29:32.323-06:00 server-db-01 syslog-ng 29213 - [meta sequenceId="2733718"] debug Incoming log entry; line=
A normal log message then follows the '=' sign.
A decent percentage of my messages are preceeded by this throughout the day, but just before the disconnect it appears that all of my messages from server-db-01 are preceeded by the debug line. Any ideas as to what could be going on? I have included my config file below if that helps.
Any assistance would be greatly appreciated. -Jim
