BIG-IP (all modules)
Fixed In:
21.1.0.3, 17.5.1.10, 17.1.3.6
Opened: Mar 30, 2026 Severity: 4-Minor
On every TMM start, /var/log/ltm contains: err tmm[<pid>]: 01010007:3: Config error: Error updating categories in urlcat err tmm[<pid>]: 01010007:3: Config error: Error updating categories in urlcat items err tmm[<pid>]: 01010007:3: Config error: Error updating categories in classification The triplet repeats twice per TMM and is logged by every TMM instance.
This issue results in cosmetic log noise only and may trigger monitoring systems that parse /var/log/ltm for error-severity or 'Config error' strings. It does not affect URL categorization, filtering, classification, or traffic processing.
- Install BIG-IP 17.1.3.1. - Occurs with any provisioning or licensing combination (reproducible with LTM-only). - The issue arises during every TMM start, including boot, upgrade, or upon running bigstart restart tmm.
