Opened: Aug 30, 2017
Severity: 3-Major

Symptoms

system memory can be exhausted and the kernel will kill processes as a result.

Impact

The kernel will kill any number of processes; any/all critical applications could become non-functional.

Conditions

During live-install, if configuration roll-forward is enabled, and the compressed configuration size is of a similar order of magnitude as total system memory.

Workaround

Make sure there are no un-intended large files included in the configuration. Any file stored under /config is considered part of the configuration. If the configuration is, as intended, on the same order of magnitude as total system memory, do not roll it forward as part of live install. Instead, save it manually and restore it after rebooting to the new software. to turn off config roll forward; setdb liveinstall.saveconfig disable to save/restore configuration manually; see https://support.f5.com/csp/article/K13132
