TL-SG108E V3, 1.0.0 Build 20171214 Rel.70905

After a few hours or perhaps a day or so, the ping time to the switch from a local computer goes from 2ms to 240ms. When this happens, the Easy Smart Configuration Utility ver 1.1.1.0, will intermittently loose contact with the switch with the message "Timeout, no response from agent!". Rebooting the switch fixes the problem but only temporarily.

Is there any way to find out what is going on in the switch when this happens?

ping results at 2 second intervals:

Edit: It seems this occurs when the Easy Smart utility is left ON. The problem has not returned since I closed the utility.
