Re: Apache 2.4 (Apache Benchmarking) - Too many open files (24)

[Rubén Toribio Aldeguer <rtoribio@xxxxxxx>]

Are you testing from de same host that runs httpd?

Could you paste paste the output of ulimit -a  , ie:

[apache@----------- ~]$ ulimit -a

core file size          (blocks, -c) 0

data seg size           (kbytes, -d) unlimited

scheduling priority             (-e) 0

file size               (blocks, -f) unlimited

pending signals                 (-i) 30504

max locked memory       (kbytes, -l) 64

max memory size         (kbytes, -m) unlimited

******   open files                      (-n) 1024

pipe size            (512 bytes, -p) 8

POSIX message queues     (bytes, -q) 819200

real-time priority              (-r) 0

stack size              (kbytes, -s) 10240

cpu time               (seconds, -t) unlimited

max user processes              (-u) 1024

virtual memory          (kbytes, -v) unlimited

file locks                      (-x) unlimited

In rhel default seems to be 1024.

Hi,

This is my mpm conf:

<IfModule mpm_event_module>

    ServerLimit             80

    StartServers             3

    MinSpareThreads         75

    MaxSpareThreads        250

    ThreadsPerChild         25

    MaxRequestWorkers      2000

    MaxConnectionsPerChild   0

</IfModule>

The issue occurs even upon increasing the serverlimit and MaxRequestWorkers.

Access log has the following status:

 [22/Sep/2016:20:17:21 +0530] "GET /cgi-bin/script.cgi HTTP/1.0" 200 16

Please check and let me know.

Thanks ,

RS

This can be related to some limits reached on the server side (cgi
connection/execution time, MaxRequestWorkers, ...).
Any error message in httpd?

Regards,
Yann.
