        <pre>Upon an unknown condition systemd-journald starts to eat 100% of CPU.
strace shows the following:

read(8, 0xbfd1238b, 8192)               = -1 EPIPE (Broken pipe)

And so on.
Distro is Arch Linux x86-32 running on x86-64 system if this matters, systemd
version is 197.
If I restart systemd-journald, the CPU is not freed.

My case look very similar to the situation discussed here -
