[syslog-ng] TCP recv bug in syslog-ng v2.09?

[Clayton Dukes]

Hey guys,
Are there any known bugs for syslog-ng v2.09  that won't allow a cisco
router to send logs over tcp?
I can see a connection established in syslog-ng.
I also see the message come in via tcpdump, but nothing in syslog-ng's
output.
If I change the router from tcp to udp, messages come in as expected.

*Router config:*

logging source-interface Loopback0
logging 172.18.224.150 <tricon:40,-1|172.18.224.150;majoshi at cisco.com>
logging host 172.18.224.190
<tricon:40,-1|172.18.224.190;majoshi at cisco.com>transport tcp


*syslog-ng config:*

source s_all {
        udp();
        tcp(ip(11.31.130.99) port(8002) max-connections(300));
        tcp(ip(172.18.224.190) port(601) max-connections(300));
};


*debug output:*
I commented out the line above for the other interface (11.31.130.99),
restarted and this is all I see:
Syslog connection accepted;
from='AF_INET(14.3.23.50<tricon:40,-1|(14.3.23.50;majoshi at cisco.com>:63845)',
to='AF_INET(172.18.224.190 <tricon:40,-1|(172.18.224.190;majoshi at cisco.com>
:601)'


*tcpdump:*

14:13:46.914566 IP (tos 0x0, ttl 251, id 4303, offset 0, flags [none], proto
TCP (6), length 134)
    14.3.23.50.63845 > xxx.com.601: Flags [.], seq 230:324, ack 1, win 4128,
length 94
