Comment (by zhenmue):

 Well, we are a hosting provider with at least 2-3 thousand Wordpress
 Sites.

 During the past months we have seen this specific issue very random trough
 our clients.. maximu 1 or 2 every 3-6 months, nothing that big.

 But in the last 3 days?, we have seen it in at least 30+ clients, trough
 different servers, different wordpress versions, different php versions,
 etc.

 All Servers running CloudLinux, Cpanel, LiteSpeed.

 It's a difficult issue, since it's not just filling the error_log up to
 the Disk space of the plan, but also maxing out the Disk I/O of the plan,
 and the RAM.

 We have been able to "fix" (not really a fix) the majority, just tweaking
 the error_Reporting value, but this is not a real solution.

 This Bug affects at least from what we have seen:
 Wordpress 4.9 5.0 5.1 5.2
 PHP 5.6 7.0 7.1 7.2
 Cpanel 80+
 LiteSpeed Latest
 CloudLinux latest
