[BUG] <io.netty.util.internal.OutOfDirectMemoryError>

[whirring]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

Same as Question#4274

I used Shenyu 2.4.1 in our production environment, for tps lower than 20 per second

this bug first appeared at 24.7.30, shenyu-bootstrap jvm options -Xmx2g -Xms2g -Xmn1g -Xss256k

then I temporarily changed jvm memory to -Xmx4g -Xms4g -Xmn1g -Xss256k

but at 24.11.21, this debug appeared again, logs goes like below

Expected Behavior

I think maybe ByteBuffer in netty not released finally

we only used divide, context_path, sign and monitor plugins

Steps To Reproduce

No response

Environment

ShenYu version(s): 2.4.1
