Problem observations / language specific caches

[ccsmart]

Some problem observations that may or may not be related:

A node process is stuck with high CPU load apparently feeding into systemd-journal:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
30998 gawatis+ 20 0 2894236 1.456g 13960 R 99.3 15.2 3545:45 node
343 root 20 0 118564 46184 45836 R 99.0 0.5 2696:47 systemd-journal

This one:
gawatis+ 30998 1 35 Mar27 ? 2-11:06:44 /usr/bin/node ./bin/www

These messages in large numbers seem related:

@ccsmart no not missing file ... there is a logical check messing for a fallback locale file. Will add that.
