Affected Product(s):
BIG-IP ASM, AVR
Known Affected Versions:
14.1.4.5, 14.1.4.6, 14.1.5, 14.1.5.1, 14.1.5.2, 14.1.5.3, 14.1.5.4, 14.1.5.6
Opened: May 27, 2022 Severity: 3-Major
The BIG-IP may log errors similar to the following: Apr 20 06:22:30 bigip1 crit tmm3[6615]: 01010025:2: Device error: n3-compress0 Zip engine ctx eviction (comp_code=4): ctx dropped. Feb 1 08:53:00 bigip1 crit tmm1[25889]: 01010025:2: Device error: n3-compress1 Zip engine ctx eviction (comp_code=6): ctx dropped.
If these logs are not occurring frequently and are being caused by AVR they can be safely ignored. It is difficult to determine whether these messages are related to AVR or part of a hardware problem with the Nitrox. With AVR debugging enabled the following log message can be observed: <13> 2022-04-22T15:21:30.836+02:00 bigip1 notice AVR: AVR decompression failed (most likely out-of-memory or bad format, err=32)
When AVR is in use, a Nitrox accelerator card is installed in the BIG-IP.
