Opened: Nov 09, 2015

Severity: 3-Major

Symptoms

Large compressed files can cause qkview to consume large amounts of memory.

Impact

Memory usage might be greater than 350200 kilobytes, which is the critical memory level. Might force other processes into swap. This can negatively impact performance.

Conditions

Less than 10% of system memory available or less than 96 KB of memory available. Large compressed files in qkview.

Workaround

None.

Fix Information

None

Behavior Change

qkview will abort if there is insufficient memory available for it to execute (less than 10% of total memory). This is so that the operation does not negatively impact memory in other BIG-IP system processes. If a qkview is required and there is insufficient memory, the -F option can be specified on the qkview command line, which will force the execution.
