Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - circut_breaker - 02-24-2010 08:19 AM
Welcome,
One of my users get trouble with his application using ispCPOmega.
He run some external programs using shell_exec, but execution of that commands took about 4 - 10 minutes.
In this time, application have to be working, with established database connection, after fetching result decide what to do next...
My first step like sys admin was configure in php.ini of his file right amount of resources (ram) and allocate additional time limit for executing his application.
Thats how it looks:
Code:
max_execution_time = 2200;
max_input_time = 2200;
memory_limit = 2512M;But he still got errors about Internal Server Error 500.
So i check log files and found that reason is too short time of execution fcgi.
So i made little changes in file called
Code:
/etc/apache2/ispcp/DOMAIN_NAME.confThat's how it looks after my changes:
Code:
# Any changes made to this file will be preserved.
# ispCP doesn't and won't verify the contents of this file.
#
# This file should NOT be deleted, otherwise apache will fail to start
#
<IfModule mod_fcgid.c>
AddHandler fcgid-script .php .php5
SocketPath /var/lib/apache2/fcgid/sock
IdleTimeout 36000
IdleScanInterval 32400
BusyTimeout 33000
BusyScanInterval 320
ErrorScanInterval 6
ZombieScanInterval 30
ProcessLifeTime 7200
SpawnScoreUpLimit 100
SpawnScore 1
TerminationScore 2
MaxProcessCount 250
DefaultMaxClassProcessCount 1000
DefaultMinClassProcessCount 0
IPCConnectTimeout 3600
IPCCommTimeout 72000
MaxRequestsPerProcess 5000
</IfModule>I had rebooted server several times.
But my user still getting Internal Server Error 500...
And log files says:
Code:

If someone have any idea... i'm open, i will listen to anything...

RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - kilburn - 02-24-2010 11:41 AM
AFAIK, different fcgid versions support different subsets of directives in the VirtualHosts sections. This is, depending on your fcgid version, it is possible that a "BusyTimeout" directive inside a "VirtualHost" section (as you have it) does not override the base "BusyTimeout" set globally.
Try to apply your modified settings globally (in the /etc/apache2/mods-enabled/fcgid_ispcp.conf file) and see if it makes a difference. If true, you've found the problem. Otherwise you got me!
RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - circut_breaker - 02-26-2010 03:41 AM
Welcome.
I just now try Your solution.
First i edit global file
Code:
/etc/apache2/mods-enabled/fcgid_ispcp.confNow it have following content
Code:
<IfModule mod_fcgid.c>
AddHandler fcgid-script .php .php5
SocketPath /var/lib/apache2/fcgid/sock
# IPCConnectTimeout 200
# IPCCommTimeout 600
IPCConnectTimeout 1200
IPCCommTimeout 1200
</IfModule>After change, reboot server.
When it start, i run test script and found following errors:
Code:
[Thu Feb 25 18:21:48 2010] [notice] mod_fcgid: process /var/www/virtual/DOMAIN_NAME/htdocs/converter.php(31397) exit(communication error), terminated by calling exit(), return code: 0
[Thu Feb 25 18:21:48 2010] [notice] mod_fcgid: process /var/www/virtual/DOMAIN_NAME/htdocs/converter.php(18361) exit(communication error), terminated by calling exit(), return code: 0
[Thu Feb 25 18:22:00 2010] [notice] mod_fcgid: process /var/www/virtual/DOMAIN_NAME/htdocs/converter.php(26067) exit(communication error), terminated by calling exit(), return code: 0So it still don't work like I want.
Do you have any other ideas ?
Is there any diagnostic tool what will show current configuration of fcgi ?
- maybe then we find what's wrong with timeout...
Regards

Apply all your settings, not just these two (at least BusyTimeout is required too). I'm afraid that I don't know any way to display fcgid's effective configuration :S
RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - circut_breaker - 02-26-2010 06:34 AM
Do You know what kilburn ?
After putting all my code and of course reboot i think it start's working.
I don't want be happy to soon but as i said it's look working.
I think Your solution help, Thank you
But i still can't understand why... why when i put these lines in config of "website" it wont work...
I know that master override slave config files, but if master was empty... why that don't use all parameters from slave ?
Who knows...

After one day... stop working...
Code:
/converter.php(13926) exit(communication error), terminated by calling exit(), return code: 0Same error...
I have no idea...

First of all, check that the config hasn't been regenerated by the panel (reloading the previous settings or something).
As a workaround for this user, you might allow his website to execute external applications (see disabled_functions in php.ini). Then, he can call his converter script from the website by forking (double-forking might be necessary here) to the background and letting the conversion script just run without stopping the frontend script. The first thing to try would be just running something like:
Code:
exec('/path/to/background/converter.php file.input file.output 2>&1 >/path/to/stdout.file &');RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - circut_breaker - 03-02-2010 05:31 AM
I checked config files, there are not changed after reboot.
Everything look like in posts above.
kilburn - My user already use shell_exec.
I have also try edit edit fcgi starter.
Code:
/var/www/fcgi/MY_DOMAIN/php5-fcgi-starterCode:
PHP_FCGI_TIMEOUT=1200
export PHP_FCGI_TIMEOUTBut it won't help...
Question remain open :-(

RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - kilburn - 03-02-2010 06:10 AM
The final "&" appended to the command is the key here. It's supposed to relieve the command to the background, so that the fcgi call can end as expected while the converter keeps working until finishing...
RE: Long time execution -exit(idle timeout), terminated by calling exit(), return code: 0 - circut_breaker - 03-03-2010 10:33 PM
I see Your point but it's override trouble not solve.
I need solution for my problem, many people around the world use fcgi for conversion and i don't see why it shouldn't work longer than few minutes...
I need have running php because i want grab output
Code:
$output = shell_exec('something');And after finish i want import that output into database...
I know i can rewrite whole application, and execute commands like that
Quote:$output= shell_exec('sometghing > output.txt');and ever if php / fcgi will be killed i can re-spawn it and read output.txt to get status...
I know, i can workaround this... but why... it should work... and i want it in normal way...
