           Summary: systemd-journald eats 100% CPU
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: synytsky at fastmail.net
          Hardware: x86 (IA32)
            Status: NEW

         Component: general
           Product: systemd

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

read(8, 0xbfd1238b, 8192)               = -1 EPIPE (Broken pipe)
clock_gettime(CLOCK_REALTIME, {1361395609, 750800535}) = 0
clock_gettime(CLOCK_REALTIME, {1361395609, 750835989}) = 0
writev(6, [{"<46>", 4}, {"systemd-journald", 16}, {"[19796]: ", 9}, {"Sleeping
for 514709548 ms", 25}, {"\n", 1}], 5) = 55
epoll_wait(7, {?} 0xbfd145dc, 1, 514709548) = 1
read(8, 0xbfd1238b, 8192)               = -1 EPIPE (Broken pipe)
clock_gettime(CLOCK_REALTIME, {1361395609, 750990449}) = 0
clock_gettime(CLOCK_REALTIME, {1361395609, 751025885}) = 0
writev(6, [{"<46>", 4}, {"systemd-journald", 16}, {"[19796]: ", 9}, {"Sleeping
for 514709547 ms", 25}, {"\n", 1}], 5) = 55
epoll_wait(7, {?} 0xbfd145dc, 1, 514709547) = 1
read(8, 0xbfd1238b, 8192)               = -1 EPIPE (Broken pipe)
clock_gettime(CLOCK_REALTIME, {1361395609, 751180501}) = 0
clock_gettime(CLOCK_REALTIME, {1361395609, 751215977}) = 0
writev(6, [{"<46>", 4}, {"systemd-journald", 16}, {"[19796]: ", 9}, {"Sleeping
for 514709547 ms", 25}, {"\n", 1}], 5) = 55
epoll_wait(7, {?} 0xbfd145dc, 1, 514709547) = 1
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 -
