The ResidentSetSize is just reporting the maximum RAM used by the job so far. A ResidentSetSize of 3.5GB agrees with your report that the job causes swapping on a machine with 4GB of RAM, but can run successfully (depending on what else is is using memory on the machine).
When the Image size events cease, it means the job's RAM usage has plateaued or declined. The job is still running. If it was running for longer than expected, maybe additional load on the machine slowed down execution (due to contention for CPU or RAM).
