[Bug 879902] Re: Increase the number of inotify watches

[Eshwar Andhavarapu]

Its a simple fix to change the number right, so something stopping
someone from creating a patch and then presenting it here. I don't know
which file to change or so on but the process must surely be simple
unless the change is being debated?

Title:
  Increase the number of inotify watches

Status in “procps” package in Ubuntu:
  Confirmed

Bug description:
  Many of the problems I encountered seem to be related to a single issue : the maximum number of watches inotify is able to handle.
  I have found that the default maximum number of watches is way to low too handle every feature using inotify, a default Ubuntu uses a great number of watches out of the box and in Natty and Oneiric it starts to become a real problem.

  Possible effects are :
  - Ubuntu One not syncing correctly
  - Nautilus not updating itself when a file is created or deleted.
  - Audio players not updating music libraries
  - tail -f or other programs using inotify show a cryptic message about no space being left on the device (while there's plenty of space)

  I have found that simply doubling the maximum of watches *is not
  enough* for a normal use, and if I believe this comment :
  https://bugs.launchpad.net/ubuntu/+source/beagle/+bug/115801/comments/4
  there is no problem to setting the number of watches to a high value.
  My current setting is 524288, which is 64 times the default value, It
  may be too high for a default value but I believe that 65536 or 131072
  should be enough for almost everyone.

  If Precise Pangolin wants to be predictable, this issues *has* to be
  addressed.
