 Posted: Sat 25 Aug '12 0:32 Post subject: apache 2.4.3 idle httpd.exe procedure and not exit automatic |
 |
|
After restart apache2.4.3,the httpd.exe procedure will add one procedure.
And,if stop apache service,the httpd.exe procedure doesn't exit.You can monitor via windows task procedure monitor.
How to solve this bug?  |

| Can't reproduce this. If the process is in use (serving content to a user, maybe huge file download?) I could imagine it not stopping till that is done. |

gl,
My OS is win2003 server.
You can reproduce that.
I try that at the light or less loading time of the apache server serveral times.
1.open win task monitor window
2.restart apache
3.You can see there are four httpd.exe procedure at task monitor window.
4.If you stop apache,the httpd.exe exists still for a long time. |

4 processes? There can be only 2 unless you run 2 instaces on different ports.
With mod fcgid 2.3.6 I had the issue that 1 of the 2 procces of httpd did not die because of the faulty mod fcgid. With the bug fix in 2.3.7 it is gone (linux and windows) |

I use mod_fcgid 2.3.7 for apache 2.4.x downloaded from apachelounge.
But,the httpd.exe can't exit automatic after restart .It leaves 2 procedures still.
Maybe the mod_fcgid2.3.6's issue comes back again?I try two or more machine that all run apache2.4.x and mod_fcgid 2.3.7. |

Doubtful, but in 2.3.7 there is a secondary new feature for killing processes. Of course they have to be processes started by mod_fcgid.

I think it's just On or Off, it's off by default so
FcgidWin32PreventOrphans On
would turn it on. |

gl,
I mean that httpd.exe can't exit automatic,not mean to php-cgi.exe
When I restart apache2.4.3,the httpd.exe is still left one or two procedures at task window.The numbers of httpd.exe will increase to 4 procedures.
The other side,I make a test to stop the apache service manually,I find the win task manager,there is one or two httpd.exe is left never exit finally. |

The not ending php-cgi process can make that the httpd.exe process does not finish.
Did you try the FcgidWin32PreventOrphans On ? |

This issue occurs still after adding FcgidWin32PreventOrphans On.
The error message is :"failed application httpd.exe,2.4.3 version,failed module libapr-1.dll."
What does stop httpd.exe exit after restart apache? |

| Bad module maybe? Try without any third party modules. Still happen? |

Doubtful..
I can't image why does the cpu usage increasing to 13% while the httpd.exe process becomes idle at task manager.Then,the error shows.I can't visit the webpage at that time.

Nightmare again.
Faulting application httpd.exe, version 2.4.3.0, faulting module libapr-1.dll, version 1.4.6.0, fault address 0x00013583.
I hope it's not memory leak..
Is it possible to recompile mod_fcgid.so to solve memory leak? |

I see nothing pointing to mod_fcgid in that error. When mod_fcgid barfs, it usually shows;
Faulting application httpd.exe, version 2.2.17.0, time stamp 0x4cc68b7f, faulting module mod_fcgid.236.so, version 2.3.6.200, time stamp 0x4cd30355, exception code 0xc0000005, fault offset 0x00004b82, process id 0xc6c, application start time 0x01cb850aada19a87.
I see libapr-1.dll in that error. It could be any one of hundreds of things since apr handles so much. All disk access, memory access, you name it, it's apr handling it.
google up the exception code and see what that tells you. |

After I change to use AH"s mod_fcgid.so,here is the error message again.
| Code: | | Faulting application httpd.exe, version 2.4.3.0, faulting module ntdll.dll, version 5.2.3790.4937, fault address 0x0004ce5a. |
I google the "fault address 0x0004ce5a",But can't find it.
Before,I use apachelounge's mod_fcgid.so,I get "Faulting application httpd.exe, version 2.4.3.0, faulting module libapr-1.dll, version 1.4.6.0, fault address 0x00013583" message.
I don't install more modules.
I just install mod_antiloris,mod_security,mod_fcgid those third party modules only.
The strange thins is that I can't find error message at apache error.log.
I can't explain why does the fault messages appear after change two kind of mod_fcgid.so only. |

I reproduce this issue from win7 randomly.It occurs at win2003 server sp2 too.But,it doesn't occur at win xp sp3.
The image link here.
Many httpd.exe(apache2.4.3)processes idle there,and no respond to phpinfo.php with the increasing idle process after several times restart.
I have added those directives. | Code: | <IfModule mpm_winnt_module>
ThreadsPerChild 150
MaxRequestsPerChild 0
</IfModule>
AcceptFilter https none
AcceptFilter http none
EnableSendfile Off
EnableMMAP off
|
The issue exists still.
Anyone can help me,please?
best regards
