Infinite stall in UnrealPak with large files writing IO Store

Development Pipeline & Plugins

If a IO Store file being packed by UnrealPak is larger than the MaxSourceBufferMemory in FIoStoreWriteRequestManager then the Writer will wait indefinitely in FIoStoreWriteRequestManager ::Start for room in the buffer leading to the application just spinning and logging a stalled status forever.

I will caveat this by stating I think my 4GB .ubulk terrain file is erroneous and I am in the process of trying to figure out why our Linux Server has this file while our Windows Client doesn’t seem to, but regardless I would have preferred an error and a failure than indefinite stalling of UnrealPak leading to our builds mysteriously timing out for an unknown reason.

Correcting some of my claims here.

This doesn’t seem to be Linux Server specific, this file is large in our Windows client as well. I don’t know why it paks correctly for the Windows Client.

It still shouldn’t be that large, I am still looking into that part.

Hi David,

Is it possible for you to share your log file when running UnrealPak.exe?
