[R] Anybody know the cause of this?

[James Plante]

Just upgraded to R 3.3.1; when I updated the packages on CRAN, I got a BUNCH of warning messages like the ones below:

2016-07-01 14:44:19.840 R[369:3724] IMKClient Stall detected, *please Report* your user scenario attaching a spindump (or sysdiagnose) that captures the problem - (imkxpc_windowLevelWithReply:) block performed very slowly (2.40 secs).
starting httpd help server ... done
> spindump()
Error: could not find function "spindump"
In addition: Warning message:
In library() :

This is not interfering with any of my work, but I’m curious to know what it’s warning me about. 
Two more questions: 1) What’s a spindump; and 2) What’s a sysdiagnose? 
And finally, how would I get either one of those, and to whom would I send them?

Thanks,

Jim
