Hi Matt, we configured 24GB as xms and xmx parameters. For now we have a normal use of memory without OOM errors. Thank you, Fortunato ... View more

Hello Matt, Nothing was changed in the last month: the environment we are using for the memory issue is isolated and not used. At this moment only one flow is scheduled. I can enable the java arg 13 that is disabled. #java.arg.13=-XX:+UseG1GC Can this issue be related to the open version of java? openjdk version "11.0.20" 2023-07-18 LTS OpenJDK Runtime Environment (Red_Hat-11.0.20.0.8-1.el7_9) (build 11.0.20+8-LTS) OpenJDK 64-Bit Server VM (Red_Hat-11.0.20.0.8-1.el7_9) (build 11.0.20+8-LTS, mixed mode, sharing)   Thank you, Fortunato   ...

Hello Mat, thank you for your support. We have a 3 node cluster (NiFi version is 1.19.0) and the scenario I'm presenting is the one with a unique execution of a single flow, scheduled to run once a day. The flow is an ETL type (no http jetty instance is invoked). The issue is that the ram occupancy, not increment at the same time for each run and remains high even if the flow is not running. We have tested the flow for one month. The ram occupancy was stable for 3 weeks and in the last one we had the abnormal consumption of the java process invoked by nifi service. Since the last week, the ram occupancy was not decreased. Thank you, Fortunato ... View more
