--- Comment #7 from schapra...@hpi.de --- Same observation here. Piped logging (for CustomLog) results in segmentation fault of worker process. Running: Apache/2.4.62 (Debian) SVN/1.14.2 OpenSSL/3.0.15 mod_fcgid/2.3.9 mod_qos/11.74 mpm_event enabled on Debian 12. Tried it out with very easy piped scripts (with dedicated bash |$ and without |): CustomLog "|$/usr/bin/tee -a /tmp/asdf.log" vhost_combined PS.: log file was present before start of apache as it was created in advance. This is typically what you find in the error log. [Thu Apr 24 16:06:22.569119 2025] [core:notice] [pid 1219940:tid 1219940] AH00052: child pid 1266782 exit signal Segmentation fault (11) AH00106: piped log program '/usr/bin/tee -a /tmp/asdf.log' failed unexpectedly PS.: Even a redirection of stderr to stdout using 2>&1 does not help.
