alloc::boxed::Box<F,A> as core::ops::function

There is too little memory to allocate, resulting in an OOM (Out of Memory) error.

Do other TiKV nodes in the cluster have similar issues? Is it an occasional phenomenon or a frequent event? Has the latency and QPS of business access been affected?

| username: 哈喽沃德 | Original post link

The configuration is too low.

Is this related to memory?

| username: lemonade010 | Original post link

It’s probably a memory issue with std::thread::Builder::spawn_unchecked_::{{closure}}::{{closure}}.

Out of memory

| username: TiDBer_KugsyWcF | Original post link

But the memory did not spike.
At the same time, there are two “monotonic time jumped back” errors. I don’t know if they are related to this.

Why does the time rollback issue occur? What’s this about? Let’s start another thread to discuss it.

| username: TiDBer_KugsyWcF | Original post link

Is it possible that this issue is caused by a time rollback?
