Question

I have a function or number of functions that are running at a certain time during each day which is bringing the site down. What is easiest way to search through my thousands of custom and default functions which come with WordPress so that I can reduce the manual time on my end to find these errant functions?

Answer 1

few ways to tackle this

1. mysql – enable mysql slow query logging
2. apache – enable mod_status with ExtendedStatus On, and prepare a crontab to log the apache process around 6am
3. linux – use another crontab to log activity captured by ps afx during that 6am time span
