AW: Code 499 and ab tools

[Andrea Soracchi]

Hi,

I get the same error...

In my sysctl.conf I set other parameters:

net.ipv4.tcp_fin_timeout      = 1
net.ipv4.tcp_tw_recycle       = 1
net.core.rmem_max             = 16777216
net.core.rmem_default         = 16777216
net.core.netdev_max_backlog   = 262144
net.core.somaxconn            = 262144
net.ipv4.tcp_syncookies       = 1
net.ipv4.tcp_max_orphans      = 262144
net.ipv4.tcp_max_syn_backlog  = 262144
net.ipv4.tcp_synack_retries   = 2
net.ipv4.tcp_syn_retries      = 2


Do you think the problem is on the server where I run tne apache benchmark?

Thanks,
Andrea

Hi,

try to increase the maximum number of open files on the server where you run the apache benchmark test.

For example temporary "ulimit -u unlimited"

Regards Frank

Betreff: Code 499 and ab tools

HI,

I am testing one of our production server with ab (ab -n 1000 -c 150  "http://www.myserver.com") and what I get is:

...
Completed 400 requests
Completed 500 requests
Completed 600 requests
Completed 700 requests
apr_socket_recv: Connection timed out (110)
Total of 743 requests completed

In the nginx's error log no output, while in the nginx's access log report 499 code (the client has closed the connection).

Where is the problem, nginx server or client ab?

Any idea?

Thanks a lot
