Subject [users@httpd] Apache 2.2.3 on Redhat AS4 instable
Date Tue, 19 Sep 2006 17:41:34 GMT
-----BEGIN PGP SIGNED MESSAGE-----

Hello,

I've installed Apache 2.2.3 on a Redhat Advanced Server 4 (with all
updates installed). You can look at the configuration log at
<http://wwwtest.uni-muenster.de/config.log>.

Every quarter or so, a client dies with one of the following lines in
the error log (lines broken by me):

    httpd: ../../../libraries/liblber/io.c:516: ber_get_next: Assertion
      `ber->ber_buf == ((void *)0)' failed.

    httpd: ../../../libraries/liblber/io.c:710: ber_get_next: Assertion
      `0' failed.

often followed by something like

    [Tue Sep 19 18:52:12 2006] [notice] child pid 20794 exit signal
      Aborted (6)

This also happens if I disabled all LDAP modules during configure.

I do not need any LDAP functionality at all, thus I tried to circumvent
the problem by configuring with "--without-ldap", but that caused the
configuration of apr-util to fail because srclib/apr-util/configure
understands "--without-ldap" as "--with-ldap=no" and looks in the
directory "no" for LDAP libraries.

Another phenomenon, maybe completely independent from the problem above:

After graceful restarts, often two or more of the following lines
appear in the error log:

    [Tue Sep 19 18:52:13 2006] [error] (9)Bad file descriptor:
      apr_socket_accept: (client socket)

After this message appears, often about half of the HTTPD child processes
keep owned by root instead of changing their identity to the user given
in the config file.

The problem is nasty because it causes more and more connections to hang
indefinitly (until the browser times out).

I already spent hours searching the internet, but without success.
Thus I dare to present my problem here. Can anybody help me?

Thanks in advance!
