Hi, I have problem with actual version od Apache HTTPD server 2.4.53. There is a problem with segmentation fault when I simulate heavy load. Problem is in event mpm. HTTPD is running as no root user. There was no problem (same problem) when I used previous version 2.4.52 with same setting and same dependencies. But we found same issue as was solving in 65769, so i try new version with hope that this was solved. But it seems that there is another problem in event mpm. Unfortunately I have no root privilages at this time, so I have limitation for take threads dump and other necessary information. So I have only question now, if is there anyone else who have similar problem?
