15.1(0.26)T 15.1(1.10)T 15.1(1.2)PI13d 15.1(1.4)T

Description (partial)

Symptoms: When rsa-sig authentication is used and CRL revocation check is enabled, IKE will be stuck till PKI comes back.  As a result, processing of packets might get delayed or packets might even get dropped due to a longer time spent in the priority queues.

Conditions: This happens with rsa-sig authentication when CRL revocation check is enabled. IKE will be stuck for a longer time if the CDP server is not reachable or the CRL data being fetched is too hugh and arrives at a slow rate.
