Full_Name: Raymond S Brand Version: 60720f5d9cdc19092d0aad6b0a94e196e5525d1c OS: Debian Wheezy amd64 URL: Submission from: (NULL) (50.88.155.14)

When run with the bdb, hdb, and mdb backends, test062-config-delete intermittently succeeds but more often than not it fails. It is the only test that has failed in my testing.

Test system, a VirtualBox instance: Linux LDAP 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux 2 VCPUs; 1.5GB

VirtualBox host system: Linux LDAP 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux 2 CPUs (Core 2 Duo); 8GB

Both O/S's are current with respect to Debian updates.

Build options: ../../configure --prefix=/tmp/ol --enable-perl --enable-overlays --enable-bdb

When run with full logging, the last line of the server log file appeared to be corrupted.

This is a sample run:

The following is the output from valgrind for the above run. Valgrind was used specifically to aid in creating this bug report; it is not part of my normal testing of this software.
