Linux system running VirusScan Enterprise for Linux run slowly or stop responding under heavy load

ProblemA linux system is intermittently slow due to heavy load, and could become unresponsive when archive files such as .jar are scanned by the On-Access Scanner (OAS).
System dump analysis shows many application processes are waiting for the completion of the OAS, as seen in the following example stack trace: PID: 28675 TASK: ffff88013c5f0ae0 CPU:2 COMMAND: "sm_sender"System event logs from the Web UI or ePolicy Orchestrator server show some .jar files timed out during OAS. The following is an example of message seen in the event log: "Timeout scanning /usr/java/jdk1.7.0_67/jre/lib/rt.jar for user root using /usr/java/jdk1.7.0_67/bin/java" CauseScanning archive file such as .jar files requires high CPU resources, and can sometimes result in scan timeouts. The process that was attempting to access the file is suspended. A timeout event occurs, then the scan request is released from the scanning queue in the kernel.
SolutionMcAfee recommends that you add .jar files or other common archive file types be added to the OAS exclusion list. For details, see PD24617.
