[CentOS] Apache error

2012-05-22 Thread Luigi Rosa
I have a VMware virtual machine with CentOS 6 32bit updated to the lates patches

Yesterday Apache started to give this error:

 Ciao,
 luigi

my guess is this is a non base package apache install or you changed 
something in the settings.
you updated the kernel a few days ago and now an issue with file locking.
that is what I got from the threads I read...
I don't know about your set up though.

keep plugging away, whatever it is should be simple to fix once you find it.

Did you update any packages ... we released a new nfs-utils package
yesterday.

Googled for two days before writing on this list.

Everything I found was about Gentoo compilation errors, old Suse issues and
apr installation issues

Needless to say, I already reinstalled Apache and apr and disabled many modules.

You might try reinstalling apr and apr-util, which may have the functions
you need.

I see there's also an libapreq2, but I'd install the two I just mentioned
first, then restart apache.

Yes, the x86 version because the server has an x86 CPU:

apr-1.3.9-3.el6_1.2.i686

I don't know if it's needed for that. Sorry, I haven't run into this, and

yea , but uninstall makes a rpmsave that likes to add the previous 
changes (or least it seems to in some cases).
I usually look for rpmsave, delete them then reinstall just in case.

Still puzzled because the VM with this issue is a clone of a VM that I have at

that one has problem with apache.

I don't think you need to post the full strace output to the list, just
the needed bits.  It can get rather large.  See man strace if you need
to have strace do individual child process debugging in separate files.

That fails install debug packages and use gdb.  You'll find the
answer...

 Ok, the strings command gives the same result.

It should just for a pointer...

  # Do not do a gracefull restart here! service httpd stop service hpptd

 got a lot of
 Process 32565 attached

Should also strace all subprocesses off the parent

 grep returns an empty set, there is no 'apr' in the entire httpd.txt
 Some (I suppose) relevant parts:

You want to look for errors also.  You could post the entire thing to a
pastebin that bit is basically the start up.  If it is still doing it
the error should be in there and may be socket related also as your was.

But be aware that some Parent Processes are not aware of there Subprocs
and thus they can not be seen by the parent.  So that entails the error
will not be in the log!

Before you go any further:

httpd is running here
lsof |grep httpd
...
all process listed here

service httpd stop
lsof|grep httpd
...should show no processes listed
if you see any listed theres your problem maybe.

Your problem seems related to an older apache problem.
