Opened: Nov 25, 2015
Severity: 2-Critical

Symptoms

With certain signatures, RSA verification can hang the Nitrox crypto accelerator chip. Errors in the ltm log show crit tmm[11041]: 01010260:2: Hardware Error(Co-Processor): n3-crypto2 request queue stuck

Impact

Nitrox crypto accelerator can hang.

Conditions

RSA verification with certain signatures.

Workaround

None

Fix Information

The Nitrox crypto accelerator will no longer hang when performing RSA verification.
