Performance Issues

[EthanKC]

I'm running Mirth Connect version 4.5.1. There are two channels running; one has processed a total of 1,093 messages. The other has processed 3,839,066 messages.
I've been seeing some performance issues recently, but I'm not really seeing errors. Late last week, I experienced a few times where the Administrator wouldn't close, and I had to end the task in task manager, then start the service again to get things working correctly. Then this morning, I tried to open the Administrator, and it just got stuck on the loading window after I put in my password. It may have eventually loaded, but after maybe 5 minutes I ended the task in task manager, and started the service. I was then able to successfully launch the administrator, but when I did there were over 600 messages queued up. They started processing right away, and from what I can tell there weren't any issues with the receiving side, it just seems like Mirth stopped being able to run successfully.
I see some errors in the logs last week, but I'm not sure the timing of those errors matches up with issues I was seeing (see below). However, there are no errors from earlier today when it wasn't launching, and apparently wasn't processing messages. Any thoughts on what might be causing these issues?
