Something was run in Diag > Command Prompt that tried to return more data than the php limit allows.

@stephenw10 Hmm, I wasn't running anything in command prompt then, though I did have a command prompt open that I had used to execute a dig command weeks earlier. I wonder whether command prompt leaks? Also via top I noticed some ping processes that I had created via the command prompt weeks ago, still hanging around. Some had ~64M memory usage.

Is there any logging of what was run in command prompt?

No directly, no.

If you run ping there be sure to specify a count. Any commands run there must have a limited time or output set.
