Ridiculously large (350GB+!) log file

For whatever reason, Studio generated a 400GB large log file.

I suspect it would be larger if it weren’t for the fact that my SSD hit max capacity. Before this one, it also generated a 400MB one. I was unable to open the new large file (or attach it) due to its size, however I had a look in the 400MB one and found that it was largely filled with messages like this:

I didn’t note any unusual activity in studio and only noticed this due to my computer acting up due to being out of storage. I am using the roblox beta channel.

The 400MB one looks to be from September judging by the dates in the logged lines, and the logged line corresponds to a bug we think we resolved back then, so it should be unrelated to the 385GB file from yesterday. If this happens again I have sent instructions on how to capture a useful subset of the file so we can identify the problem. Until then I’m going to close this report as “Incomplete.”

Thank you both for the bug reports. We have released a mitigation which should prevent this log spam from happening in new Studio sessions. Please let us know if you encounter this issue again.

Thanks for the quick fix. Out of curiosity, what was the spam?

Basically: we have a feature which tracks its memory usage and logs if it exceeds a certain amount. A bug caused the amount of consumed memory to appear crazy large which meant that log line would always activate. That usage check operation was very common, so we ended up emitting a crazy number of log operations.
