Apache SIGABRT on Gentoo

By , last updated July 30, 2015

I’ve been trying to set up a PressBooks test site on my Gentoo dec box. I may or may not write a book about programming, but PressBooks is a WordPress plugin for writing and exporting books. I was curious and decided to give it a go.

All day I’ve been trying to export a book to get a feel for PressBooks. Both to get a feel for it, and to see if this is something worthwhile or if I should be looking at other solutions.

The SIGABRT

The problem I’ve been having was that each time I tried to export the book, in either format (It being PDF, mPDF, ODT, XML or whatever), I got an error from the browser saying it didn’t receive any data from the server.

This was the response from Chrome.

No data received

ERR_EMPTY_RESPONSE

It was a similar message with Firefox.

The connection was reset

The connection to the server was reset while the page was loading.

  • The site could be temporarily unavailable or too busy. Try again in a few moments.
  • If you are unable to load any pages, check your computer’s network connection.
  • If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Whats happening on the server is that the Apache child process dies a painful death.

The errors

That this was a rather severe error was quite apparent by the no response errors from both Chrome and Firefox. The server logs for this domain where also empty, neither the domain_access_log or domain_error_log had any information about this issue. It was as it never happened.

Upon further inspection, the general server error_log (usually /var/log/apache2/error_log) was recently modified, and lo and behold, this error revealed itself in all its glory.

[Sat Jul 25 19:39:07 2015] [error] child died with signal 6

Gathering clues

To begin with, the interesting parts are the first and last lines.

  • *** Error in `/usr/sbin/apache2': free(): invalid next size (fast): 0x00007f9041de1280 ***
  • [Sat Jul 25 19:39:07 2015] [error] child died with signal 6

Anytime a free() fails, that’s a strong indication there is something seriously wrong.

In this case, the probable culprit is a heap or stack corruption bug in some modules running within Apache. It is almost never a bug within Apache itself.

The stack trace gives us some clues about what might be happening.

The stacktrace (backtrace) show us the steps leading up to the point of crash. There is no doubt the crash happened in libc, but as with Apache, there is almost never something wrong with system libraries. Those are used throughout the system and an error here would occurred somewhere else too, and not only in Apache.

The likely reason why libc is failing is because there was a failing assert in libc.

We can investigate this with gdb. Start GDB with the .so file as argument, like this gdb /lib64/libc.so.6. By using the offset from the backtrace, we can look up the closest symbol in the .so file.

Type info symbol 0x7b1e2 to find what method resides under the first frame in libc.so.

# gdb /lib64/libc.so.6

(gdb) info symbol 0x74893
__libc_message + 723 in section .text of /lib64/libc-2.20.so
(gdb) info symbol 0x79f56
malloc_printerr + 182 in section .text of /lib64/libc-2.20.so
(gdb) info symbol 0x7b1e2
_int_free + 1826 in section .text of /lib64/libc-2.20.so

Indeed, the first error message about there being something fishy with free() was not mistaken. However, we must dig deeper to find something more useful.

And about that digging deeper. I was curious on how PressBooks works when exporting a sample book, not that curious into debugging Apache and PHP.

The issue turned out to be some conflict with mod_svn and mod_php. All I had to do was disable mod_svn, as I’ve moved on to Mercurial and Git a long time ago.

In the /etc/conf.d/apache2 file, remove -D SVN from APACHE2_OPTS.

Restart Apache2 with /etc/init.d/apache2 restart and then everything was OK.
