hal-acl-tool burst of process creation/termination

[Angelo Borsotti]

Binary package hint: network-manager

Periodically, I see bursts of process creation and cancellations from hal-acl-tool. E.g.

15:0:1.111506635 fork pid 27484 parent: 27454 /usr/lib/hal/hal-acl-tool

Apparently, hal-acl-tool creates a sequence of processes to run polkit-read-auth-helper,
processes that last few milliseconds. This occurs periodically, slowing down applications.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't start working on it yet, because your bug report didn't include enough information.

The many lines that mention /usr/lib/policykit/polkit-read-auth-helper are related to the policykit package. Marking assignment to network-manager as incomplete. Assigning bug to policykit.

Please include the information requested at https://wiki.ubuntu.com/DebuggingNetworkManager. If you have trouble, please do not hesitate to ask for more assistance. Thanks in advance.
