      During service stop I periodically get errors "pipe has ended".

      It happens when stopping the service from services MCC or from task manager.

      In such cases there no "... stopped" messages written to native zabbix_agentd.log about termination. Only this:

      Some weird errors there, I see, but they should not affect service termination.

      Targeted host is a VM, OS Win7 x64, I can keep it in this state to reproduce the issue later.
      Agent from official MSI package x64, tested version 6.0.1
