No heartbeat error while performing Homogeneous refinemement

Hi,
I get the error below while performing refinement on a set of particles. The other job types (like 2D classification, ab-initio, etc.,) have executed fine till this point. The error message is below:

Launched job nEbcgQ5qRTXnFHCMB
ERROR: No Heartbeat
This job was killed because a heartbeat was not received for 120 seconds.

The last 100 lines of the job standard output are printed below.
