I am running 10.9.3 and Mail 7.3 and it quits unexpectedly, mostly overnight.

Question

When I come down in the morning and try to check my mail, it has quit unexpectedly.  It always restarts and works as usual but this seems to happen each day = the log says as follows [early and most relevant parts, I think] - any ideas on what is going on?  I can't decipher this.

Hi meyek,
I have seen this issue occur if you have improper permissions to /Library/Preferences/com.adobe.PDFAdminSettings.plist file.
Could you please take a backup of the file and then try deleting this file and then start the installation?
Regards,
