Yosemite Beta 10.10.5 (14F6a) Question

I’m currently running Yosemite beta 10.10.5 (14F6a) but have had some crashing upon quitting Mail for the past couple months.

I see two log items in Console and I’m not sure is they are causing the problem. Any insight is appreciated:

7/26/15 4:34:10.566 PM SpamSieve[1582]: Extra preferences file should probably be deleted: /Users/scott/Library/Preferences/com.apple.mail.plist

7/26/15 4:34:11.510 PM mdworker[368]: (Import.Normal:1288) Using too many resources after 256 files (wired: 0 resident: 399144 swapped: 2 regions: 1141), hit usage threshold importing /Users/scott/Library/Mail/Bundles/SpamSieve.mailbundle/Contents/Resources/LeopardTrainSpam.scpt, exiting to clean up now.

Which application is crashing? If it’s SpamSieve, please make sure that you are using the built-in crash reporter. If it’s Mail, please see this page.

I don’t think either of these is a problem.

Appreciate the feedback, I’ll be focusing on Mail for a fix.
