If you are upgrading anyway, you should see how far you can upgrade. The current version is 7.2 (with 7.4 due shortly based off the current 7.3)

There are a lot of cleanups and a new config language that can significantly clarify more complex configurations in the new versions.

Great. That was exactly my problem.

But nevertheless - I will upgrade as suggested by Gerhard.

Try starting rsyslog with the -x option to disable DNS lookups. If that solves
your problem, check that you have reverse DNS working well. Rsyslog will try to
lookup the IP address of the system sending the logs to it.

Some additional information:

We see the data coming on UDP with tcpdump in time on the rsyslog server, so we 
know, that the cisco device logs everything in time. Just the log data in the 
log file is with delay.

Betreff: [rsyslog] Input from udp/514 - output appears in logfile with delay

Hi,

We have a rsyslog 5.8.1:

Input comes on UDP/514 (from a cisco device), output is directed to a logfile - 
but there it appears with a delay from about 60 seconds.

This is a low-throughput input, so maybe, our file buffer just fills to slow.

Can I configure that somewhere so that this is written with short delay to my 
logfile ?

I've found:
$OMFileFlushInterval

But the documentation for this parameter is not useful at all ("Defines a template 
to be used for the output.") for me.
I've tried setting this to "1" - but the delay is just about 1 minute (ok, maybe the 
"1" does mean minutes, not seconds....)

Any Ideas ?

Uli
