The check of whether the open file limit needs to be changed is not
|
|
|
bdfc20 |
right, it checks the hard open file limit against what autofs wants
|
|
|
bdfc20 |
to set it to which is always less than this value. Consequently the
|
|
|
bdfc20 |
open file limit isn't changed.
|
|
|
bdfc20 |
|
|
|
bdfc20 |
autofs should be changing only the soft open file limit but it is
|
|
|
bdfc20 |
setting both the hard and soft limits. The system hard limit is much
|
|
|
bdfc20 |
higer than the autofs maximum open files so the hard limit should be
|
|
|
bdfc20 |
left alone.
|
|
|
bdfc20 |
|
|
|
bdfc20 |
While we are here increase the requested maximum soft open file limit
|
|
|
bdfc20 |
to 20k.
