BIG-IP Virtual Edition becomes completely unresponsive under very heavy load.
Traffic through the guest stops until the guest/BIG-IP system is reset. However, this issue is reproduced during a test that over provision a 2-vCPU guest and is unlikely to happen in normal operation.
Sustained high packet rate with a very small payload.
Try ones of the following workarounds (first on is the most preferred and so ): 1. Increase guest memory. 2. Significantly reduce the value of the content in '/sys/module/unic/rx_queue_size'. For example running the following command substantially decreases throughput: echo 1048576 > /sys/module/unic/rx_queue_size. 3. Set panic on OOM. Try this as the last option. sysctl vm.panic_on_oom=1
BIG-IP Virtual Edition becomes unresponsive under extreme load test due to kernel memory exhaustion from over-provisioning.
