When i trying to open .php page i see blank page. .html pages showing normal.

I have no idea how to fix it. Please help me.

Do you use ISPConfig? If so, take a look here: http://www.howtoforge.com/forums/sho...29&postcount=7

Exactly same problem. After I changed what falko proposed I get errors:

(9)Bad file descriptor: apr_socket_accept: (client socket)

during reload (when I change something in configuration so apache configuration is reloaded). And after that when I click on some PHP site I get error:

[notice] child pid XXXXX exit signal Segmentation fault (11), possible coredump in /tmp

If I manualy restart apache everything works fine (If I just reload, still get same error).

Any Ideas?

Is there a coredump in the /tmp directory?

Yes, I think so. There are some core.XXXXX files in /tmp directory.

What's in the latest one?

Hm. Where should I open this file? If I open in editor it has ureadable format...

and it's about 82 Mb huge file.

Matej

p.s. Temporary I use (bad) "workaround". I changed script /root/ispconfig/scripts/lib/classes/ispconfig_system.lib.php to "restart" apache instead of reload. Becouse this is dirty workaround I would be very greatfull if we can find solution for my problem

I know this is an old thread but I figured I'd bring it back to life.

I'm currently experiencing the same issue and cannot really figure out what's happening.

I've enabled the CoreDump using this tutorial:

http://www.cyberciti.biz/tips/config...core-dump.html

I can then read the GDB core dump via gdb with the following:
gdb httpd -c core.8352

The part where apache fails is at the end of the dump:

Code:

Reading symbols from /usr/lib/php/modules/pdo_sqlite.so...done.

Loaded symbols for /usr/lib/php/modules/pdo_sqlite.so

Error while mapping shared library sections:

%0*Zx, 0x%0*Zx): No such file or directory.

Core was generated by `/usr/sbin/httpd'.

Program terminated with signal 11, Segmentation fault.

[New process 7688]

#0  0x011aee2b in ?? () from /etc/httpd/modules/libphp5.so

I've tried to disable a couple of the modules by renaming them, but the same issue keeps happening. Anyone have any idea/tips on how I can identify the culprit and get this working correctly?

as a side note I'm on PHP 5.1.6 and Apache 2.2.3 using MPM worker.

This may be caused by a conflict between php dynamically loaded modules and apache included modules.

Check out the pdo manual, uninstall either the php modules from php repository or debian repository.

Old post but I recently hit this issue after installing php5-sybase on Ubuntu Lucid.

Turned out my syntax for mssql_connect was incorrect. I was using double quotes and should have been using single.

so ensure check your documentation and ensure your syntax is correct.
