Error description
Worklight Server may run out of memory when the server logs are configured to be forwarded to analytics server according to http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.1.0/com.i bm.worklight.deploy.doc/admin/r_analytics_properties.html?lang=e n java.lang.OutOfMemoryError and java.lang.OutOfMemoryErrorException may be printed in the log file. Memory heap file may be filled with the "com/ibm/ws/logging/object/WsLogRecordImpl" objects. Additional Keywords: Worklight Versions Affected: 6.x Initial Impact: High
Local fix
Disable the problematic code by using wl.analytics.logs.forward=false This feature is enabled by default.
Problem summary
**************************************************************** * USERS AFFECTED: * * Administrators of Worklight servers that are configured to * * forward server logs (which is the default setting) to the * * analytics platform. * **************************************************************** * PROBLEM DESCRIPTION: * * The Worklight server is configured to forward server logs to * * the analytics platform by default. Because the server can * * log before some internal features are loaded, the log data * * must be queued in memory. The queue size is unlimited, and * * therefore may run out of memory when the server is set to * * high verbosity logging, but the log forwarding feature is * * not yet initialized. * **************************************************************** * RECOMMENDATION: * * - * ****************************************************************
Problem conclusion
The code has been updated to limit the size of the in-memory queue so memory cannot be exhausted in the problematic code path.
Temporary fix
