Re: [Mod-fcgid-users] Fwd: mod_fcgid with php CGI hangs on interrupted downloads

2011-02-22 Thread Liam O'Boyle
Hi Josiah,

There was a strace snippet in the linked serverfault page, as follows

root@some-machine:~# strace -p 24837
Process 24837 attached - interrupt to quit
write(3, 
\5|A\313%\35\337\376\275\237\230\266\242\371\37YjzD\322\215\357\336:M\362P\335\242\214\341...,
17432

Just hanging on that, or something like it, each time.  I assume this
is blocking trying to write back to the fcgid handler.

Thanks,
Liam

 Subject: mod_fcgid with php CGI hangs on interrupted downloads
 To: mod-fcgid-users@lists.sourceforge.net


 Hi there,

 I'm having an issue with downloads through PHP when using mod_fcgid;
 if the download is interrupted before it's complete, the php-cgi
 process seems to block until the execution timeout is reached, rather
 than aborting immediately.  Further requests to the server by the
 same user that interrupted the download hang until the process aborts
 and the php-cgi process starts serving more requests, but requests by
 other users do not appear to be affected.

 It doesn't appear to be a PHP problem, as the same code, when run
 using mod_php, executes correctly.

 Does anyone have any suggestions that I could look into to fix this?

 A full explanation is up on ServerFault -

 Thanks for any help,

 Liam

Liam,

Someone else commented that you should increase the value of your 
IPCCommTimeout setting; I'd recommend this as well, though I have to ask, as 
these uploads taking multiple minutes to complete or do they hang fairly 
quickly?

Morning,

They hang whenever interrupted; if a download would have taken 2
seconds and I cancel it, then the PHP process will hang until the
timeout is reached; the same behaviour is observed with files of all
sizes.

I don't have any solutions for you, but I'd recommend trying to discover where 
or why it's hanging. The tool 'strace' would be most useful in figuring this

The ideas that come to mind off the top of my head are problems with file size,

2011-02-21 Thread Noor
Hi Liam,

Try adding this to the VirtualHost configuration for the intended website:

IPCCommTimeout 300

In addition, I'd recommend starting with a bare-bones Apache (without any
additional 3rd party module, like Suhosin and others) and then activating
only FastCGI with PHP. Best is when you compile PHP from sources.

I run Apache 2.2, FCGI, PHP5 on Debian and have no issues for years. The
only difference than your configuration is: I compile PHP5 from sources.
Actually I do that all the time in FreeBSD servers, but since Debian is a
development machine, I only build PHP5 from sources.

/Noor
