Post 7.1.1 upgrade errors in Log

Getting lots of these errors in the PHP log after upgrade to 7.1.1. At the rate these are generating my log is going to be over 2gig before end of day.

Any suggestions?

some are just notices which I wouldn’t worry about, maybe just you reporting level to include show notices, they only real error appear to be you max_exceution_time, which you could increase in you php.ini, but 600 seconds seems a reasonable amount to me, maybe the performance of the server this running on that is causing this to be exceeded
