Subject: [PATCH] coredump: raise the coredump save size on 64bit systems to
|
||
|
|
32G (and lower it to 1G on 32bit systems)
|
||
|
|
|
||
|
|
Apparently 2G is too low for various real-life systems. But raising it
|
||
|
|
universally above 2^32 sounds wrong to me, since that makes no sense on
|
||
|
|
32bit systems, that we still support.
|
||
|
|
|
||
|
|
Hence, let's raise the limit to 32G on 64bit systems, and *lower* it to
|
||
|
|
1G on 32bit systems.
|
||
|
|
|
||
|
|
32G is 4 orders of magnitude higher then the old settings. Let's hope
|
||
|
|
that's enough for now. Should this not be enough we can raise it
|
||
|
|
further.

||
