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

[Rubén Toribio Aldeguer <rtoribio@xxxxxxx>]

25 * 2000 = 50.000 threads. May be you have to setup ulimit in your OS.

Hi,

Below is the issue encountered when i am trying to use apache 2.4 to validate performance using the benchmarking tool(ab tool).

ab is invoked with 2000/1000 concurrent requests and subjected to 80000 cgi requests. The module enabled is mod_cgid. Occurs with worker/event mpm enabled

MPM configuration is:

<IfModule mpm_worker_module>

    ServerLimit             80   

    StartServers             3

    MinSpareThreads         75

    MaxSpareThreads        250

    ThreadsPerChild         25

    MaxRequestWorkers     2000  

    MaxConnectionsPerChild   0

</IfModule>

================================================

2000 concurrent requests

Benchmarking x.x.x.x (be patient)

socket: Too many open files (24)

OR 

1000 concurrent requests

Benchmarking x.x.x.x (be patient)

Completed 8000 requests

apr_socket_recv: Connection timed out (110)

Total of 8972 requests completed

================================================

This occurs on RHEL as well as on HP-UX.

Please help if anyone has encountered the same problem.

Thanks,

RS
