- ActiveIQ Unified Manager (AIQUM) 9.6及更高版本
问题描述
- OnCommand Unified Manager Web界面变得陈旧、无响应、并停止从其受监控集群收集数据
- 由于服务器几乎无法正常运行、不会触发事件/警报

- 在某些情况下 、AIQUM服务可能在重新启动后根本无法启动
在支持包的"jjBoss"文件夹中、查看"au_error###.log"文件中的以下内容:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 12288 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: Knowledgebase
# 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
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
