The number of inotify watch instances available is limited system wide
|
||||||
|
via a sysctl setting. It is possible for certain processes, such as
|
||||||
|
pypi-server, or elasticsearch from the ops repo to consume a large number
|
||||||
|
of inotify watches. If the system wide maximum is reached then any process
|
||||||
|
on the host or in any container on the host will be unable to create a new
|
||||||
|
inotify watch. Systemd uses inotify watches, and if there are none available
|
||||||
|
it is unable to restart services. The processes which synchronise the repo
|
||||||
|
server contents between infra nodes also relies on inotify watches. If the
|
||||||
|
repo servers fail to synchronise, or services fail to restart when expected
|
||||||
|
check the the inotify watch limit which is defined in the sysctl value
|
||||||
|
fs.inotify.max_user_watches. Patches have merged to increase these limits,
|
||||||
|
but for existing environments or those which have not upgraded to a recent
|
||||||
|
enough point release may have to apply an increased limit manually.
