That is good to hear.
Several people have posted patches or enhancements to the list with no
reaction from the maintainers. In the past i have also submitted
patches/enhancements for maui and i got a reaction if the patch will be
applied or rejected. Some patches also fixed issues in moab ;-)
To give an example. I have posted a patch that fixes an issue with MAXPS
for our site. I submitted a bug report and asked several times to the
list if the patch will be applied, rejected or must i change the patch
so it would be applied. Till now i have not had a reaction at all ;-(

Somebody has to make the decision to apply a patch. Who makes the
decision? The community is a bit vague ;-).

To trigger the segv, you do not need a big cluster at all. I run it on a
test cluster with 2 nodes and adjusted MAX_MJOB to 32768 and submit a
lot of jobs and see if maui could cope with it. So it is a simple test.

Could this also be a team instead of one person?
