OS: Linux CentOS 7
RAM: 16GB
Software version installed: Apache IoTDB - [All-in-one] - 1.0.1

I am encountering the following error(java.lang.OutOfMemoryError: Java heap space) while running the instance of IoTDB.
How can I resolve this?

There are many reasons that may cause OOM. Current information is not enough to locate the issue.
However, as far as I know, there is some memory leakage in the query process of v1.0.x.
So, if your workload has many query requests, try to upgrade to v1.1.x, and let's see whether the issue is solved.

Hi @jixuan1989,
Thank you for the reply.

if your workload has many query requests,

I am continuously(24/7) inserting some time-series test data to the IoTDB using the REST API service provided by IoTDB. On 8th day I got the above "java.lang.OutOfMemoryError: Java heap space" error.
Also, w.r.t query requests I make query request through Grafana to view the test data collected in IoTDB but it is very minimal.

try to upgrade to v1.1.x, and let's see whether the issue is solved.

Since I am using Grafana version v7.5.17, I was not able to use IoTDB v1.1.x version.
Will try to see if I can upgrade to the IoTDB v1.1.x version with compatible Grafana-Plugin supporting Grafana v7.5.17.
