I've been having a same sort of issue that others have reported. After
dhclient has been running for a random length of time, it suddenly
starts consuming a large amount of CPU. Unfortunately for me, the
longest it tends to run is 48 hours before acting up.
I did get it rebuilt with debug symbols, and got a stack trace from it,
while it was acting up. Hopefully, it will be useful.
Attaching to program: /sbin/dhclient, process 2248
