Continuously log all function calls to file?

[ashiklom]

I'm trying to use this package to diagnose a nasty hang that shows up seemingly at random (or at least, is hard to reliably reproduce). Something that would be useful for that is to have a log of every command that Emacs executes, dumped to a file in chronological order (i.e., as the commands happen). That seems to be well within the capabilities of this package, and seems to be the point of explain-pause-log-to-socket. However, I haven't been able to get that command to work: Every time I try to run it, I get the error:

Explain-pause-mode stopped logging to socket. It got too full.

I've tried this with both the default and custom explain-pause-logging-default-location, with the same results.

Am I interpreting this feature correctly? And, if so, could you provide an example configuration / a brief explanation of how to set it up?
