Affected Product(s):
BIG-IP All
Known Affected Versions:
17.1.3
Opened: Nov 06, 2025 Severity: 1-Blocking
On Azure instances with high interface count (6 or more) Mellanox linux kernel driver mlx5_core may fail to initialize the interface or attach it very slow. Another symptom of this problem: packets drops because of timeouts in Mellanox device queue processing. mlx_core will report multiple errors in the kernel logs (run "dmesg | grep mlx5_core" to display it).
- Azure instance starting time may be significant - SSH access may be unavailable - Packets drops on dataplane Mellanox interfaces
- BIG-IP VE instance deployed in Azure with 6 or more interfaces - Accelerated networking is enabled
