Hi Willy,
Please find attached a tgz containing the following:
* Output from "strace -o log -tts 16384 -p $(haproxy_pid)"
* Full packet capture of all port-80 traffic (client is on 10.0.2.82)
* Log output from client identifying corrupt file
* Modified config file used in this test
For this test, only IPv4 was used. Client side MSS is forced to 1300
by an intermediate firewall.
Please let me know if any further information would be useful.
Charlie
Looking at the strace, the following jumps out as being odd:
A partial write succeeds, writing the remaining data fails with EAGAIN.
The send is then retried with what looks like a corrupt buffer.
