thank you. I could reliably reproduce this problem actually so I am not
sure if it is really caused by syslog-ng (and not by servers in
question). 

Because I do not want to lose klogd functionality I currently use

source sys      { unix-stream ("/dev/log"); file
("/var/lib/syslog-ng/klogdpipe" log_prefix ("kernel: ")); internal(); };

where /var/lib/syslog-ng/klogdpipe is FIFO. That was actually a reason
for a fifo vs. pipe question :-)
