要約
The instance may crash, become slow, or become unresponsive.
The following entries can be found in the atlassian-jira.log:
Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled.
Java HotSpot(TM) 64-Bit Server VM warning: Try increasing the code cache size using -XX:ReservedCodeCacheSize=Note: An instance might still be impacted by this issue even when the above error is not present in the logs.
The following appears on the thread dumps where the compiler threads would be in the runnable state and consuming CPU.
Note: In JDK 1.8 and above these threads are no longer present
"C2 CompilerThread0" #6 daemon prio=5 tid=0x000000001ab9c000 nid=0xcfc runnable [0x0000000000000000]

原因
This issue can occasionally happen when the Java CodeCache becomes full.
ソリューション
Modify setenv.sh or setenv.bat accordingly ( if you've already increased to 1024m, increase to 2048m )
# The following setting configures the size of JVM code cache. A high value of reserved size allows Jira to work with more installed apps. # JVM_CODE_CACHE_ARGS='-XX:InitialCodeCacheSize=32m -XX:ReservedCodeCacheSize=1024m'- Clear catalina.out log file under <JIRA_INSTALL>/logs directory because the health check may be responding to outdated messages in catalina.out.
Restart the application for the new settings to take effect.
