I had done a 'make clean' before, but I think I found the problem when looking through the config parameters. Instead of my config file, I used the example one and it didn't segfault. I narrowed it down to the 'destination' parameters which seem to need a variable like ($HOST or $FACILITY) in the destination file (havent tried this version with other destinations than files). In my config I had destination path names like '/var/log/tcp.log'. When I changed that to '/var/log/$HOST_tcp.log' it didn't die anymore. Can you reproduce this behaviour? Apparently It doesn't matter where a variable is present on each line, but it needs one on every destination. I proceeded with testing the SIGHUP problem and as far as I can see your patch works perfectly. I tested as I had done before and there was no loss of logs. I even stress tested a bit by sending 10 HUP's per second while syslog-ng received five million rows (@25000 rows/sec) from another server. Everything still worked fine :) Thanks for your help on this! // Martin On Dec 3, 2007 7:09 PM, Balazs Scheidler <bazsi@balabit.hu> wrote:

Hmm... I encountered a similar error in my tree when I forgot to "make clean" before recompiling. Can you check if you do a make clean and then recompile the above problem goes away?
I also have Ubuntu 7.10 installed and it works for me:
