I can report that a recent ppa update has improved this issue for me, now it idles at around 2% CPU. However strace still shows significant flooding of EAGAIN.

And it wastes power too of course. When connecting to the process with strace to see what's going on, here's what we get repeating as fast as the terminal can print it: stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3543, ...}) = 0 read(7, 0x13a9eb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 13) = 0 (Timeout) read(7, 0x13a9eb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) read(7, 0x13a9eb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 0) = 0 (Timeout) read(7, 0x13a9eb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) And /etc/localtime on my system is this: root@ubuntu:~# ls -l /etc/localtime lrwxrwxrwx 1 root root 30 2010-06-04 09:37 /etc/localtime -> /usr/share/zoneinfo/US/Central So it should be valid. Using lsof indicates nobody is using the file.
