Version: 1.21z-5
Severity: grave
Hi,
sometimes when I start chrony it goes into an endless loop. It uses
100% cpu but according to starce it does no system calls. gdb shows
the following:

And syslog shows this:

Removing /var/lib/chrony does does not help. As soon as chrony picks a
source it loops.
