Actually, it also can be, that your commit limit is reached. Can you also
look in the /proc/meminfo -> CommitLimit and Commit_AS. These values should
not be too close to each other.
What are the values
for /proc/sys/vm/swappiness, /proc/sys/vm/overcommit_memory
and /proc/sys/vm/overcommit_ratio? What is your swap size. They all
influence CommitLimit and the amount of memory, you can get.
