参数比较多的时候,多线程回测到一半总是 崩溃,pycharm的错误日志如下。
用的 是12核 16G内存的,虚拟内存也改到很大了。 这可怎么破?

There is insufficient memory for the Java Runtime Environment to continue.

Native memory allocation (malloc) failed to allocate 1089456 bytes for Chunk::new

Possible reasons:

The system is out of physical RAM or swap space

The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap

Possible solutions:

Reduce memory load on the system

Increase physical memory or swap space

Check if swap backing store is full

Decrease Java heap size (-Xmx/-Xms)

Decrease number of Java threads

Decrease Java thread stack sizes (-Xss)

Set larger code cache with -XX:ReservedCodeCacheSize=

JVM is running with Zero Based Compressed Oops mode in which the Java heap is

placed in the first 32GB address space. The Java Heap base address is the

maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress

to set the Java Heap base and to place the Java Heap above 32GB virtual address.
