Плимут check gets stuck, preventing service operation

This is в strange one. If I do, say

service jenkins start

it will always freeze/get stuck, like waiting for some неудар в лунку. Same is with all services and start/stop commands. However, if I do it like

service jenkins start | cat

it will work without issues. Also piping to/dev/null works. Using set -x, гve managed to track down the freeze at

+ '[' -z ']'
+ FANCYTTY=1
+ case "$FANCYTTY" in
+ true
+ /usr/bin/tput xenl
++ /usr/bin/tput cols
+ COLS=144
+ '[' 144 ']'
+ '[' 144 -gt 6 ']'
++ /usr/bin/expr 144 - 7
+ COL=137
+ log_use_plymouth
+ '[' n = y ']'
+ plymouth --ping

And indeed, it is always plymouth --ping that freezes. Подходящий для воспроизведения It is directly from shell схвати well. Any ты разрабатываешь to troubleshoot this?

Ubuntu версия is 14.04.01. Плимут is supposed to log to /var/log/boot.log, but I don't see anything useful there, just "Stopping" and "Starting" lines that have OK схвати result.

Process list regards to plymouth looks like this:

$ ps -ef | grep plymou
root        478      1  0 Dec01 ?        00:00:04 plymouth-upstart-bridge
root        492      1  0 Dec01 ?        00:00:00 @sbin/plymouthd --mode=boot --attach-to-session
root       1710   1699  0 Dec01 ?        00:00:00 plymouth quit
root       1725   1411  0 Dec01 ?        00:00:00 plymouth --ping
root      48897   2140  0 12:12 pts/0    00:00:00 grep --color=auto plymou

strace plymouth --ping шоу this:
