Syslog-n tries to reconnect in every 60th seconds to server by default. Perhaps, the first attempt was not succes and you need wait for the second attempt so it can take 1-2 minutes. If you reduce the "time_reopen()" on your _client's_ configuration, it can be faster. I also have an other theory, if you are using flow-control on client side, and the server is a bit overloaded, syslog-ng can stop reading the source (and sending to the server). Just show a few debug lines after starting syslog-ng on client and a few lines on server in the same time. (because syslog-ng will send a few log about the state of connections, e.g.: accepted or closed) 2010.01.22. 22:11 keltezéssel, Rory Toma írta:
The problem has been alleviated somewhat by moving to a 64-bit platform. Since these generally have a different set of tcp defaults, there is probably a tcp value(s) that need tuning. I do notice on this one, that after I reboot a client, it takes a few minutes for the logs to start flowing, but flow they do.
I can show you the output, but it's quite long.

Hi,
Can you show me the output of "syslog-ng -Fevd" on your client after restarting?

I am using syslog-ng-3.0.4-1.rhel on a CentOS-5.4 system. I am using tls, and have a setup as below. Here is what happens. It logs fine. However, if I reboot my client that is sending logs, it no longer works until I restart the syslog-ng server. What do I need to do here?
