Memory consumption goes higher than heap size limit

Support

Hello,

We are currently starting to run an ERGO node v4.0.16 using docker.
The max heap size of java is correctly set as the log tells upon startup:
Picked up _JAVA_OPTIONS: -Xmx3g

However what we experience at some point is:

  • peaks of memory consumption reaching 3 GB with logs telling java.lang.OutOfMemoryError
  • then later, no more java.lang.OutOfMemoryError and the memory consumption goes up to 16 GB and even more

As a workaround, we have set a limit of memory consumption using docker itself.
But we would like to know if this is an identified problem, or if someone did experience that ?

At first glance I’d say it looks like a memory leak, so we definitely cannot use it that way at the moment.

Small update: this week-end everything went fine. We had a misonfiguration in our API key where we used a placeholder with ‘<’ and ‘>’ characters, so it’s a guess but maybe it is related to the memory leak somehow.
