[Pacemaker] lrmd fork: cannot allocate memory

[walter.pisani at erptech.it]

Thanks Lars,

I understand that i have an out-of-memory situation, but I don't' understand because swap memory is 100% free (128Gb).

Bye
Walter

Above 99.71% memory utilization? Yes, I'd say that indicates an out-of-memory situation.

Alas, this is not sufficient to reconstruct which process consumed that memory.

I'd keep monitoring this and once you go above >80% again start looking for processes that are larger than they should be.
