Hi, @Srikant May you elaborate >We have verified using top command that framework was using 2gB memory while allocated was just 50 mb.
* How many running tasks in your framework? * Do you enable or disable swap in the agents? * What's the flags that you launch agents? * Have you saw some thing like `Updated 'memory.limit_in_bytes' to ` in the log of agent?
