ERROR_IPSEC_IKE_QM_LIMIT - 13884 (0x363C)
Reached maximum quick mode limit for the main mode. New main mode will be started.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_IPSEC_IKE_QM_LIMIT (13884, 0x363C) indicates that the system has reached its maximum limit for establishing quick mode security associations during the main mode phase of Internet Key Exchange (IKE). This typically occurs when the number of simultaneous or recently established quick modes exceeds a predefined threshold.
Error Details
This error is specific to IPsec and IKE, which are used for secure communication over networks. The quick mode phase follows the main mode in establishing security associations between two endpoints. When this limit is reached, the system will initiate a new main mode to continue the negotiation process or handle additional security associations.
Usage Context
This error can occur in scenarios where multiple IPsec connections are being established simultaneously or when there has been a high volume of quick mode negotiations recently. It may also be encountered during network troubleshooting or when configuring complex IPsec policies that involve numerous security associations.
Developer Interpretation
Developers should interpret this error as an indication that the system is nearing its capacity for handling simultaneous IPsec connections. This can impact performance and resource utilization, especially in environments with high network traffic or frequent connection establishment.
