Hi there, Right now, in our cluster, we leave the Memory setting as default We un-touch all the following configs: DREMIO\_MAX\_MEMORY\_SIZE\_MB DREMIO\_MAX\_HEAP\_MEMORY\_SIZE\_MB DREMIO\_MAX\_DIRECT\_MEMORY\_SIZE\_MB Since the usage of Dremio is getting higher among our company, we’re occurring more and more memory issues, especially for Full GC ![image](https://us1.discourse-cdn.com/flex020/uploads/dremio/original/2X/f/f4449ddc70e02f1e231caf01cb52c6864113d117.png) 5k Full GC events in 1 working day ☹ And it happens on all the nodes ![image](https://us1.discourse-cdn.com/flex020/uploads/dremio/original/2X/4/4946711ad425c00ab594cbb72521c685b953ab91.png) So we want to tuning the setting for the memory I was said that depends on the role, each node will need a specific setting for the memory My cluster consists of: 1 x master: 32cpu, 96GB 1 x coordinator: 32cpu, 96GB 3 x executor: 32cpu, 372GB 3 x executor dedicated for reflection: 32cpu, 372GB We’ve tried to pump the specs of each node really hard, but seems like the misconfiguration of the memory is the root cause here Please help to advice Thank you ---

@quangth2 What kind of deployment is this? Are you able to send `ps -ef | grep dremio` output from the nodes?
