Symptoms

Mismatched IPsec policy configuration causes racoon to core intermittently after failed IPsec tunnel negotiation.

Impact

Intermittently, the racoon daemon cores and crashes when there are earlier failed phase 2 negotiations.

Conditions

During IPsec Tunnel negotiation, IKE Phase 1 negotiation succeeds and ISAKMP security association is created, but phase 2 (Quick mode) for IPsec security associations fails due to mismatched IPsec policy configuration. This intermittent error occurs because of a memory issue that causes heap corruption.

Workaround

Make sure IPsec policies such as encryption/authentication algorithms for the data going through IPsec tunnel on the remote device match the IPsec policy configured on the BIG-IP system for the same IPsec Tunnel.

Fix Information

The racoon daemon no longer crashes due to mismatched IPsec policy configuration.
