|
||
<p>A possible scenario is that the process has hit the max open files
|
||
allowed, and so trying to accept a new connection will fail with
|
||
EMFILE. In some cases, it's preferable to just wait for some time, if
|
||
the application will likely close some files (or connections), and try
|
||
to accept the connection again. If this option is true, the error will
|
||
be logged at the error level, since it is still a big deal, and then
|
||
the listener will sleep for 1 second.</p>
|
||
<p>In other cases, hitting the max open files should be treat similarly
|
||
to being out-of-memory, and simply error (and shutdown). Setting this
|
||
option to false will allow that.</p>
