我正在从虚拟Linux机器（VPS）运行JAR（例如，Talend作业）。
当我运行jar时，我正面临连接超时异常。
我无法完全解释它，因为如果我在Eclipse中运行JAR（例如在Talend ESB Studio中），它可以正常工作。 jar正在进行一些HTTP GET调用，并使用chrome dev工具测量它们从10s到40s。
在调查抛出此异常的原因时，我在jar目录中找到了一个名为 hs_err_pid6127.log 的文件，其中包含一些关于内存不足的日志，以便Java Runtime Environment继续
这是我的问题：两件事可以以某种方式联系起来吗？如何知道Java Run Time Enviroment的实际内存？这可能是超时的原因吗？如果是的话，如何解决？
JAR异常堆栈跟踪：

内存错误不足的日志文件内容：
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 179306496 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
