[Bug 65596] New: Apache Hang after some time

https://bz.apache.org/bugzilla/show_bug.cgi?id=65596

            Bug ID: 65596
           Summary: Apache Hang after some time
           Product: Apache httpd-2
           Version: 2.4.49
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Core
          Assignee: bugs@httpd.apache.org
          Reporter: pe.remy@bwagence.fr
  Target Milestone: ---

On all our servers (gentoo up to date, kernel 4.9.xxx ), apache 2.4.49 crash
silently after some time  (many hours or few days, about 2 or 3 times per week
on high traffic servers, less on medium traffic servers).
have to revert server version, no problem.
No error log at all, apache processes still up, but all http(s) requests
timeout. No firewall.

Temp Fix : revert to 2.4.48


Same problem for many users on this forum :
