I’ve got a client using The Events Calendar Pro with a significant number of recurring events (typically, 5-10+ events\/day Monday to Friday, plus a few on the weekends). The schedule has been set up through June of 2017, resulting in about 2000 posts. <\/p>\n

I started noticing timeout errors just after the site went live – usually when I was doing something in the Events Calendar. But I didn’t pinpoint it specifically to TEC at that point – I was just adding lots of events so that’s the screen I was usually on. After asking my tech support about the frequent timeouts, they checked the logs and found some issues. Part of their Email response is below:<\/p>\n

it IS clear that at least a small part of the performance problem on the existing server is the sayward site itself.<\/p>\n

Every one of those hits took approximately 30 cpu seconds to render. That
\nis NOT right.<\/p>\n

and as far as I can tell, that appears to be repeatable.<\/p>\n

ahh, it is actually failing…<\/p>\n

<br \/>
\n<b>Fatal error<\/b>: Maximum execution time of 30 seconds exceeded in
\n<b>\/raid\/home\/sayward\/sayward\/wp-includes\/taxonomy.php<\/b> on line
\n<b>1532<\/b><br \/><\/p>\n

(That 30 cpu second limit would be controlled by your php.ini
\nfile, but I highly doubt increasing it would help)<\/p>\n

hhmm, tracing one of those processes… it appears to be stuck in a
\nloop… at least one mysql query (a complex one) got run 26 times before
\nthe script ran out of CPU time.<\/p>\n

SELECT wpvos_posts.*
\nFROM wpvos_posts
\nINNER JOIN wpvos_postmeta ON ( wpvos_posts.ID = wpvos_postmeta.post_id )
\nWHERE 1=1
\n AND ( \\n wpvos_postmeta.meta_key = ‘_EventStartDate’\\n)
\n AND wpvos_posts.post_type = ‘tribe_events’
\n AND ((wpvos_posts.post_status = ‘publish’))
\n GROUP BY wpvos_posts.ID
\n ORDER BY wpvos_posts.post_date DESC<\/p>\n

Obviously, the common thread to the long running processes appears to be a
\ntrailing date parameter?<\/p><\/blockquote>\n

I did find a couple of posts about excessive CPU issues with recurring events in the forums, but the latest, from June 2016, appears to be a different issue than this, as it was creating extra posts. That is definitely not the case here. <\/p>\n

The client has a facility that runs recurring events from September to June. That was the key reason we chose TEC. Making events only recur for a month or so at a time is really not an option – this needs to be as hands-off as possible. <\/p>\n

Thanks in advance for your reply.<\/p>\n
