Caizhi Weng commented on FLINK-16636:
-------------------------------------
Sorry for all the non-sense guessing above... I've tested on {{ProcessBuilder}}
today and it doesn't seem to double the memory usage.
However, I discover a [bug
report|https://bugs.openjdk.java.net/browse/JDK-8054841] saying that there are
native memory leak issues in {{ProcessBuilder}}. From {{container.log}} the
testing JVM is indeed using a lot of virtual memory, a lot more than the
configured 2GB heap size.
{code}
[ 1641.681910] [ pid ] uid tgid total_vm rss pgtables_bytes swapents
oom_score_adj name

{code}
Here {{total_vm}} and {{rss}} are counted by 4kB blocks and it seems that one
single JVM process is using up to 5GB virtual memory and 3.7GB of anonymous
rss. Is this memory usage, especially non-heap memory usage reasonable?
Another strange thing I noticed is that the sum of total_vm or rss seems to be
larger than the container memory limit. Is this an expected or reasonable
behavior?
