@misikco if possible - could you please upgrade to latest 5.0.9 and test it?

[aria321]

In 5.0.14 I got that above exception also, there are two Redis server one of them with huge Data works correctly but in the second server there are little Data than the first one, but I am getting the Exception periodically. Why and how can resolve the problem?

[adrianchristanto]

Is there any solution or workaround for this issue? Similar problem also occur in 3.2.100
