Issue: https://github.com/php/php-src/issues/8517 Author: triplesixman ### Description Hello, Since the switch to php8.0-fpm, I have random php crashes which force me to restart it manually and cause a 502 bad gateaway error on my site. The crashes are random and sometimes occur after several days. The logs indicate this: > May 8 16:21:14 LSN-D7324 kernel: [817145.478932] php-fpm8.0[3482145]: segfault at 105 ip > 000055c8afc40309 sp 00007ffd430d3860 error 4 in php-fpm8.0[55c8af9c1000+285000] > May 8 16:21:14 LSN-D7324 kernel: [817145.550172] Code: ac 4c 8b a0 f0 00 00 00 41 0f 94 c5 89 > 4d a8 0f 84 e6 02 00 00 48 8b 45 a0 48 83 c0 70 48 89 45 88 4d 85 e4 0f 84 2d 03 00 00 <41> f6 > 44 24 05 04 75 11 48 8b 45 a0 8b 80 e4 00 00 00 41 39 44 24 > May 8 16:21:14 LSN-D7324 systemd[1]: php8.0-fpm.service: Main process exited, code=killed, > status=11/SEGV > May 8 16:21:14 LSN-D7324 systemd[1]: php8.0-fpm.service: Failed with result > 'signal'. > May 8 16:21:14 LSN-D7324 systemd[1]: php8.0-fpm.service: Consumed 3d 57min 21.700s CPU time. Unfortunately I don't have more information and it is impossible to identify the problem. Do you know how I can get more details? I have thousands of active users on my site and it will not be possible for me to reproduce the crash by myself. Thank you ### PHP Version PHP 8.0.18 ### Operating System Debian 11
