BTW, this is on the bug tracker now.
After reading the memory leak upon spell usage, I remembered that I was also receiving a memory leak, but my character doesn't use spells!
Spellcasting leaks RAM (http://www.hydlaaplaza.com/flyspray/index.php?sort=asc&order=field4&order2=&sort2=asc&project=2&do=details&task_id=4322)
So I decided to document this problem using my ever-so-helpful task manager. I noticed that half the time, when the PSClient crashes, my Memory usage for the client is at 1 million KB. There is definitely something in the code that's been continually saving data to amass to this large quantity. Unfortunately I wasn't able to get the client to crash this time (the memory dumped from the 700,000 KB to the 400,000 KB), but I was able to document it.

Notice that I have Photoshop Open as well. And that the CPU Usage is at the full 99% (Mine rarely hits 100% unless it's a major thing)

The CPU usage is down, but my Memory usage went up! Photoshop's did as well, but only because I had 2 layers in one file instead of one.

Holy cow! 700,000! Photoshop went up as well, but only because I now had 3 layers instead of 2 in one file. When my PSClient 'randomly' crashes, I notice that the Memory usage of the client exceeds 1 million! That's HUGE.
And as you will also notice, none of the other programs displayed are gaining -THAT- much Memory.
