Subject: [PATCH] debug: don't set resource hard limit to zero
|
|
|
|
Setting the resource hard limit to zero is irreversible, meaning if it
|
|
is set to zero then there is no way to set it higher. This means
|
|
enabling core dump is not possible, since setting a new resource limit
|
|
for RLIMIT_CORE would fail. By only setting the soft limit to zero, we
|
|
can disable and enable core dumps without failures.
|
|
|
|
This fix is present in both main and 3.0.x upstream branches.
