What finally mitigated the problem was locking down the number of simultaneous FTP connections to an unreasonably low number (200) and disabl= ing Apache 2.4. I think this reduced the load sufficiently to avoid the issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
