Title:
  init ran out of file descriptors, spinning while trying to start a
  broken service

Status in “upstart” package in Ubuntu:
  New

Bug description:
  After updating to 12.04 beta1, mysql service was broken.

  I noticed my fan turn on a while after running sudo service mysql
  status (never completed).

  :; sudo strace -f -p 1
  Process 1 attached - interrupt to quit
  pipe([1022, 1023])                      = 0
  open("/dev/ptmx", O_RDWR|O_NOCTTY)      = -1 EMFILE (Too many open files)
  close(1022)                             = 0
  close(1023)                             = 0
  pipe([1022, 1023])                      = 0
  open("/dev/ptmx", O_RDWR|O_NOCTTY)      = -1 EMFILE (Too many open files)
  close(1022)                             = 0
  close(1023)                             = 0
  pipe([1022, 1023])                      = 0
  .
  .
  .
  ^C

  :; sudo ls -lv /proc/1/fd | grep -c /var/log/upstart/mysql.log
  1005

  I guess this is probably the same as #940290
