You need to send more than 510 jobs to see the problem. > In both cases enable loggin invalid messages as Patrick wrote in a previous mail: > # modprobe ipt_LOG > # echo 255 >/proc/sys/net/netfilter/nf_conntrack_log_invalid Ok. > In the first case run the unpatched 2.4.24 kernel and before doing > any printing, start dumping all the traffic at the 515 port so that we > won't miss any connection and send the dump file: > # tcpdump -i lo -s 0 -w dump.pcap tcp port 515 Attached are the file dump1.bad, and dmesg.bad. The console only starts printing out the "nf_ct_tcp: invalid packed ignored" messages after the 22 seconds "pause". Look for pause at "23:40:27.454677", and resume at "23:40:59.469704". The first console message at "23:40:59". > In the second case run the patched kernel and just start printing: do you > get any 'nf_ct_tcp: invalid SYN' kernel message? No such message. Even after trying many times. But there's still a 26 "pause" from "23:49:41.368812" to "23:50:07.392278". It's able to resume and continue printing in "burst". These tests were ran with just 520 jobs using: for((i=1; i<520;i++)); do echo $i | lpr -Plp; done Sorry for the delay. Traveling.
