Hi Pierre,


I think it is a memory resource issue.


I have set the "memory_limit=-1" in php.ini and "pm=ondemand" in php-fpm.conf. It seems issue is now fixed for my low traffic websites.


Thanks for you time.

Hi Pierre,


There are 3 low traffic WP sites running on this !GB ram VPS, only this particular 1 site always has this issue.


I have set the

PHP.ini

memory_limit = -1 (unlimited)


The htop shows 400/995MB, but the issue is still there.


Thanks a lot.

Hi Pierre,


Thanks for your response.


I am using default settings:

pm = dynamic

pm.max_children = 5

pm.start_servers = 2

pm.min_spare_servers = 1

pm.max_spare_servers = 3

;pm.process_idle_timeout = 10s

;pm.max_requests = 500


This is a tiny personal stie, no heavy traffic at all. Also, I have 200MB ram available.


Thanks again.



Email forwarding also requires SMTP?

Thanks for your support!
I notice that my VPS provider blocked outbound SMTP in default. Does this cause the issue?
