Handling of multiple connections during NAT traversal for a node behind a symmetric NAT is disclosed. The likelihood of connection failure during symmetric NAT traversal may be reduced by serializing critical time windows after port prediction. Once port prediction has begun for a first connection, port prediction for a subsequent connection may be delayed until a connectivity check has begun for the first connection. This process may be repeated to handle NAT traversal for multiple simultaneous connections to different nodes.

In a memory with block management system, program failure in a block during a time-critical memory operation is handled by continuing the programming operation in a breakout block. Later, at a less critical time, the data recorded in the failed block prior to the interruption is transferred to another block, which could also be the breakout block. The failed block can then be discarded. In this way, when a defective block is encountered during programming, it can be handled without loss of data and without exceeding a specified time limit by having to transfer the stored data in the defective block on the spot. This error handling is especially critical for a garbage collection operation so that the entire operation need not be repeated on a fresh block during a critical time. Subsequently, at an opportune time, the data from the defective block can be salvaged by relocation to another block.
