Bug#666926: apache2: Error on graceful restart: "(9)Bad file descriptor: apr_socket_accept: (client socket)"

[stufo76 <stufo76@gmail.com>]

Package: apache2.2-common
Version: 2.2.16-6+squeeze6
Severity: important


every day I found this in error.log:

[Sun Mar 25 06:25:54 2012] [notice] Graceful restart requested, doing restart
[Sun Mar 25 06:25:54 2012] [error] (9)Bad file descriptor: apr_socket_accept: (client socket)

apache2 processes grows, and I need to manually restart it.
