cladera spawning lots of php processes and 100% cpu

  • In the past few days my site really started slowing down and maxing out the cpu. It spawns lots of php worker processes (sometimes up to 20 or more) that grow to max out all available memory. I’ve had caldera for several years and upgraded through all the previous version to current.

    If I do
    SELECT option_name
    FROM wpnv_options
    WHERE option_name LIKE ‘%cftransdata%’
    it gives me 35k rows

    What’s the best way to delete those rows – if its ok for me to do so?

    It seems like there is some issue with wp-cron and transients?

    Also – My php slow log shows lots of these sort of entries:

  • Same issues here. We’re experiencing some random spikes in CPU and DATABASE usage. How can we proceed to reduce that load?

    Logs are the same as wallying.

    Clearing the 35k of transients helped things immensely. But it looks like Caldera is now continuing to generate and not clear additional transients. Hopefully some of the development team can weigh in on the transient and cpu spike issue.

    We’re seeing constant updates in our database with the following query
    UPDATE wp_options SET option_value = ‘7’ WHERE option_name = ‘CF_DB’
    UPDATE wp_options SET option_value = ‘8’ WHERE option_name = ‘CF_DB’

    Is it normal?
