Thank you for your answer.
Here is the result of limits:
Resource limits (current):
cputime infinity secs
filesize infinity kB
datasize 33554432 kB
stacksize 524288 kB
coredumpsize infinity kB
memoryuse infinity kB
memorylocked infinity kB
sbsize infinity bytes
vmemoryuse infinity kB
swapuse infinity kB
swapuse is set to unlimited, but stacksize is set to 512MB.
Is it the stacksize setting that prevent my kernel to swap more then
If so, are there any side effect of raising the stack (except exhaust
the swap space on the system) to give me more time to react by
restarting NFS or export/import Zpools for example in the case of NAMEI
memory leak before the kernel crashes ?
