FMEA-005: Log Overflow Fills Disk ¶

1 Status ¶

2 Failure Mode ¶

Diagnostic logging grows without bound and eventually fills the disk the application runs on.

3 Effect ¶

Unrelated features start failing on write errors long before anyone connects the failures to the log volume.

4 Cause ¶

Log rotation was configured by size per file but not capped in total, so long-running installations accumulated files indefinitely.

5 Severity ¶

4

6 Occurrence ¶

4

7 Detection ¶

2

8 Mitigation ¶

A total cap with rotation was configured and shipped; the oldest files are dropped first and a warning is logged when the cap is reached.

9 Residual Severity ¶

4

10 Residual Occurrence ¶

1

11 Residual Detection ¶

2

12 Monitoring ¶

None; the risk is closed. Reopen if the cap warning appears in support logs.
