DiscordParser possible issue

In a recent test, I got 2052 exceptions like this printed in processing log:

Not sure if it is expected or not. Any idea @felipecampanini or @patrickdalla?

PS: An user recently reported OOM and the log suggested it came from DiscordParser. After disabling it, the user was able to process the case. Unfortunately he didn't send the heap dump I asked for to further investigate...
