OnCommand Unified ManagerのWebインターフェイスが応答しなくなる

環境

  • OnCommand Unified Manager(OCUM)9.5以降
  • ActiveIQ Unified Manager(AIQUM) 9.6以降

問題

  • OnCommand Unified Manager Webインターフェイスが古く応答しなくなり、監視対象クラスタからのデータ収集が停止する
  • サーバがほとんど機能していないため、イベント/アラートはトリガーされません。
  • OnCommand Unified Manager (vApp)の仮想マシンインスタンスをリブートしたあと、応答の速度が低下して再度リブートが必要になるまで、機能が比較的短時間再開されます。
  • 再起動後にAIQUMサービスがまったく起動しない場合があります。

サポートバンドルの「jboss」フォルダで、「au_error###.log」ファイルで次の内容を確認します。

# 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=

# This output file may be truncated or incomplete.

# # Out of Memory Error (os_linux.cpp:2643), pid=6920, tid=0x00007f30c27e9700
