Certain configuration parameters used during an SSL handshake can elicit a 'queue stuck' message from the accelerator. When this happens, the /var/log/ltm log file will contain a message similar to the following: 'n3-cryptoX request queue stuck'.
In-flight and queued contexts for the specific accelerator are dropped. After device recovery, new requests will be accelerated.
The BIG-IP system uses Nitrox 3 encryption hardware to perform SSL encryption. An SSL handshake sent to the BIG-IP system is incorrectly configured or contains bad information.
Disable crypto acceleration.
The crypto accelerator is gracefully reset when the accelerator stalls due to a misconfigured request. Note: This issue resolution is limited to SSL handshake issues, and is not a resolution for all possible causes of a 'queue stuck' event.
