event collector stops with TimeoutException error and does not restart or exit, running indefinitely until restarted manually

[Koguni31]

eNcore 5.2.4 runs and exports events for some time (from several or tens of minutes to tens of hours or several days) but stops with TimeoutException error and does not restart or exit, but several processes running indefinitely (and systemd does not see that service have failed) until restarted manually:

Before emitting error and stopping processing events, htop shows 100% vCPU usage by one of eNcore processes, this could be not related to problem, but anyway, its illustrated below:
