Yes, mod_php. I've run stack traces and didn't see anything stand out. At the bottom of this email is the last couple hundred lines of the output from `strace -o /tmp/st -s 5000 httpd -X`, the last couple lines being when I ctrl-c killed it after several minutes. Do you see anything that I'm missing? I looked through the entire log and didn't see anything, but didn't want to post its entirety here.

I've reviewed your policies, but my apologies if I break rules/conventions. Please don't hesitate to correct me.I've run into an issue where enabling the PHP SQLSRV extension [1] causes httpd to fail to start. I've documented the issue at length here [2]. The PHP SQLSRV extension does NOT impact general PHP use (command line PHP works fine). Only starting httpd will not work. As [2] says, I'm not really getting any significant error messages, so I'm not sure how to proceed. See sections "journalctl -xe output", "/var/log/secure", and "/var/log/httpd/error_log" for relevant log output. Can anyone help me troubleshoot this? Also, this setup works fine on other servers, and I can't think how this one is different.Thanks in advance,James
