Fastcgidispatch + apache : Internal server error

[Benjamin G.]

Hi,

Our configuration :

  - Solaris Sparc 64bits
  - Apache/2.2.27 (Unix) Server built: Jun 23 2014 20:53:59
  - fastcgidispatch 2.50.18 build-134114 FastCGI Dispatcher Target s640900.
  - httpd.conf :

                LoadModule fastcgi_module modules/mod_fastcgi.so
                <IfModule mod_fastcgi.c>
                     FastCgiServer /opt/fourjs/prd/gas/bin/wrapper.fcgi -idle-timeout 300 -initial-env FGLASDIR=/opt/fourjs/prd/gas
                     Alias /gas /opt/fourjs/prd/gas/bin/wrapper.fcgi
                </IfModule>
                <Location /gas>
                      Allow from all
                </Location> 

Sometime with must restart by killing fastcgidispatch process (kill -9) because all http connections are rejected. In apache_log file we've this message :

    10.10.26.7 - - [22/Apr/2016:04:32:09 +0200] "POST /gas/wa/ka/84687511362749f5ec0bdbb8c0220278/0 HTTP/1.1" 500 535
Error 500 means (internal server error).

We don't understand why this happens.
Anybody can help us to "debug" this issue ?

Thanks in advance

Have you contacted your local support contact?

Questions they may ask may include ...

- have you tried with the latest maintenance release, in this case 2.50.43
- have you tried these troubleshooting tips https://4js.com/online_documentation/fjs-gas-manual-html/#c_gas_fastcgi_install_007.html
- what is in our GAS logs with the categories.filter set to include ALL https://4js.com/online_documentation/fjs-gas-manual-html/#c_gas_asref_LOG_CATEGORIES_FILTER.html

Depending on what is in the logs, they may ask ... 
- are your ulimit values sensible?
- is the session directory corrupt?  (gasadmin -l https://4js.com/online_documentation/fjs-gas-manual-html/#c_gas_tools_gasadmin.html should be empty when the system is idle)

Even if the issue is in Apache and its configuration, there maybe clues in our log as well as the Apache logs.
