Logs Getting created

This is an odd behavior, the following logs are getting created, and is overflowing the Network, and crashing the site due to big log files:

[23-Jun-2018 08:41:27 UTC] PHP Notice: ob_end_flush(): failed to send buffer of zlib output compression (1) in /var/www/vhosts/+++.com/laurentcuchet+++.com/wp-content/plugins/wpmudev-updates/includes/class-wpmudev-dashboard-ui.php on line 1612

It’s creating 1GB logs per second with the above notices, and hence crashing the server due to big file size. I want to keep debug mode enabled, and zlib.output_compression enabled.

Would like to know a workaround to make it work, without disabling the above specified.
