500 Error On Checkout

(@dacrosby)

Hi,

I ran into a problem where Post SMTP plugin appears to be causing an error on store checkout. Customer checks out, payment is processed, admins are notified and then apparently the alowed memry size is hit before the customer notification goes out. Since there was an error, WooCommerce displays “Internal Server Error” on the customer’s page and checkout doesn’t advance to the Thank You page (even tough payment has processed).
It’s only about 4 seconds from hitting Confirm Payment to the error showing, so I don’t see why how we’d be hitting the memory limit.
I can disable this plugin and checkout proceeds correctly.

WordPress v4.9.5
WooCommerce v3.3.5
Post SMPT v1.8.9.

Here’s the error log entry, maybe someone can help figure out what’s hapening here.

Out of interest, what memory limits do you have set in the WP ini file and on the server itself?

131Mb seems to be a weird figure to run out of memory at. (i.e. it’s not set to 128Mb, so I’m guessing you have it set to 256Mb which then begs the question, why is it throwing a memory error at 131Mb + 5167bytes.

What type of hosting is this on?
What version of PHP?
What version of SQL?

If I can make a guess the email log has a lot of records.

Did you set a custom number for the email log ?

PHP v5.6.33
MySQL v5.6.39
“GoDaddy “Enterprise Busines Hosting”, Apache, cPanel

other phpinfo() :
PHP memory limit 128M
PHP exec time 30
PHP post max size 8MB
Max Upload 2MB

Post SMTP has logging enabled:
max Log entries: 250
Max Transcript Size: 128
Under Misc settings, PHP log level is set to Error and Delivery Mode is set to “Log email and Send”

I did recently switch from the old plugin, POSTMAN SMTP – would that have left some residual isues? I noticed most of the settings copied over automatically (e.g. API ley, log amounts etc)
