Opened: Mar 02, 2016

Severity: 4-Minor

Symptoms

The /var/tmp/merged.state file produced by merged when it is sent SIGUSR2 including when qkview is taken can incorrectly report the merge method as slow in limited circumstances.

Impact

It is harder to debug merged.

Conditions

The input files to merged need to be in a steady state of churn (rows added or removed) so that merged cannot successfully complete a merge.

Workaround

Reduce the churn on the input files, for example by not spawning a steady stream of processes recorded in the proc_pid_stat table.

Fix Information

None
