[GitHub] [iotdb] jansona opened a new issue, #11122: [Bug] A large number of TimeSeries creations may trigger OOM, causing termination of client connections and inter-node communication threads.
jansona opened a new issue, #11122:
URL: https://github.com/apache/iotdb/issues/11122
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.
### Version
OS: CentOS 7.9
IoTDB: 1.1
### Describe the bug and provide the minimal reproduce step
Creating 19,400,000 TimeSeries using 5 processes in Session mode.
### What did you expect to see?
During stress testing, certain requests may be rejected if the load is too high.
After the stress testing, memory is freed up and performance is restored.
### What did you see instead?
During stress testing, when the on-heap memory and off-heap memory are fully utilized, there is a certain probability of encountering OutOfMemoryError in the error logs. This can lead to issues such as failed client connections, inability to synchronize data from other nodes to the problematic node, and failed execution of write statements.

The on-heap memory has not been released for a long time:
Frequent Full GCs:
There are performance issues even if OOM does not occur, such as slow client connections, queries, and write operations, or even program becoming unresponsive until timeout.
### Anything else?
Currently, regarding the issue of OOM causing client connection failure, it has been verified through Arthas that when OOM is thrown in Socket, it is not properly handled in AbstractThriftServiceThread. The execution of the close method in the finally block leads to the closure of the thread pool.
