Hi,

I disabled prod (setting prod=0 in config), and a lot of “Couldn’t write the entire length of data” appear on my dolibarr pages.

Is there a way to properly debug/resolve?

Thank you very much.

Hello,

Can you share the exact error message and a screen ?  
What is your PHP version?

Hello,

Thanks, I never see something like that 🤔, does seems to be “normal” PHP warnings etc…

Do you have external modules ?

A quick search on google, gives some reference to PHP Share variables/memory between all PHP processes, that doesn’t make sense…
