<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)
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 -
