"Broken pipe" between Nginx and PHP-FPM

On 6th January, I updated my Drupal 8 development system (composer update). The following ls listing shows the modules that were updated.

I then went to bed and carried on working at around 14:20. Since that time I have regular errors of the following kind in my php7.2-fpm.log:

[06-Jan-2019 14:37:21] WARNING: [pool www] child 1263 said into stderr: "There was a problem sending 4325 bytes on socket 5: Broken pipe" [06-Jan-2019 14:37:22] WARNING: [pool www] child 1263 said into stderr: "There was a problem sending 178 bytes on socket 5: Broken pipe" [06-Jan-2019 14:40:23] WARNING: [pool www] child 1232 said into stderr: "There was a problem sending 178 bytes on socket 5: Broken pipe" [06-Jan-2019 14:43:55] WARNING: [pool www] child 6461 said into stderr: "There was a problem sending 178 bytes on socket 5: Broken pipe"

I have only just noticed this now whilst in pursuit of another problem. Does anyone know what might be causing it?

I’m running Drupal 8.6 on Ubuntu 18.04 with Nginx 1.14.0 and PHP 7.2.10 with FPM. The database is Postgresql 10.6.

I thought originally it might be a hardware problem, but the the immediacy of the problem after the Drupal update seems too obvious to ignore.
