ERROR_IPSEC_IKE_TOO_MANY_FILTERS - 13896 (0x3648)
Too many dynamically added IKEEXT filters were detected.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_IPSEC_IKE_TOO_MANY_FILTERS (13896, 0x3648) is returned when the system detects an excessive number of dynamically added IKEEXT filters. This indicates that the limit for such filters has been exceeded.
Error Details
This error typically occurs in scenarios where multiple dynamic security associations or policies are being established and managed by the IPsec/IKE subsystem. The system maintains a certain capacity for these filters, and when this capacity is reached, the error is generated to prevent potential instability or resource exhaustion.
Usage Context
The context in which this error might occur includes situations where multiple dynamic security policies are configured, such as during network configuration changes or when using dynamic routing protocols that require frequent policy updates. The error suggests that the system has encountered a limit on the number of dynamically added filters, which could impact performance and stability.
Developer Interpretation
Developers should interpret this error as an indication that the system is nearing its capacity for managing dynamic IKEEXT filters. This can be due to excessive or frequent policy changes, leading to resource constraints. Developers may need to optimize their code to reduce the number of dynamic filter additions or ensure that policies are managed efficiently.
Related Errors
ERROR_IPSEC_IKE_NO_CONFIG(13895, 0x3647): Indicates no IPsec configuration is available for a given connection.ERROR_IPSEC_IKE_PROCESSING(13892, 0x3644): Indicates an error occurred during the processing of an IKE message.
FAQ
Q: What does this error mean?
A: This error indicates that too many dynamically added IKEEXT filters have been detected, suggesting a potential resource limit has been reached.
Q: How can I resolve this issue?
A: Review and optimize the dynamic policy configuration to reduce the number of filter additions or ensure efficient management of policies. Consider implementing mechanisms to limit the frequency of policy changes if they are excessive.
Summary
The ERROR_IPSEC_IKE_TOO_MANY_FILTERS error code is a specific indication that the system has reached its capacity for managing dynamically added IKEEXT filters. Developers should be aware of this limitation and take steps to optimize their implementation to avoid this issue.
