Why is svchost.exe terminating my C# application?

For some reason, my C# application is being terminated by svchost.exe and I'm trying to understand why. It was terminating the application silently until I turned on Silent Process Exit logging using Gflags.exe from the Windows Debugging Tools. It happens infrequently on machines that I can't running debugging tools on (customer pcs).

The event doesn't really provide me with much info to go on. The termination code is 805306369=0x30000001, but I can't seem to find anything useful online that would tell me how to interpret that number.

I was hoping that the Silent Process Exit log would shed some light on this, but now I just have more questions.

Any advice would be appreciated. Thanks for your help in advance!

Here is the event in question:
