- Add maxKeys limit (10,000) to NodeCache to prevent unbounded memory growth - Skip caching undefined values when GeoIP/ASN lookups fail (e.g., when MaxMind DB not configured) - Add periodic cache statistics logging every 5 minutes for monitoring - Fixes memory leak where cache would grow indefinitely with high request volumes The maxKeys limit uses LRU eviction, so oldest entries are automatically removed when the limit is reached. With ~10k requests/day and 5min TTL, 10k keys provides ample headroom while preventing OOM issues. Fixes #2120

Key Features
| Connect remote networks with sites Pangolin's lightweight site connectors create secure tunnels from remote networks without requiring public IP addresses or open ports. Sites make any network anywhere available for authorized access. |
 |
| Browser-based reverse proxy access Expose web applications through identity and context-aware tunneled reverse proxies. Pangolin handles routing, load balancing, health checking, and automatic SSL certificates without exposing your network directly to the internet. Users access applications through any web browser with authentication and granular access control. |
 |
| Client-based private resource access Access private resources like SSH servers, databases, RDP, and entire network ranges through Pangolin clients. Intelligent NAT traversal enables connections even through restrictive firewalls, while DNS aliases provide friendly names and fast connections to resources across all your sites. |
 |
| Zero-trust granular access Grant users access to specific resources, not entire networks. Unlike traditional VPNs that expose full network access, Pangolin's zero-trust model ensures users can only reach the applications and services you explicitly define, reducing security risk and attack surface. |
