Hello,
I have /usr/bin/python3 /usr/bin/unattended-upgrade using 100% of a core calling
stat in a very tight loop for no apparent good reason. It does so by holding the
/var/lib/dpkg/lock-frontend lock.
Even after a kill -9, a new process shows the same behaviour.
Stracing it looks like it's in a loop calling stat for files that does not
exists:
sudo strace -c -p 6778
strace: Process 6778 attached
strace: [ Process PID=6778 runs in x32 mode. ]
strace: [ Process PID=6778 runs in 64 bit mode. ]
^Cstrace: Process 6778 detached
