Apache intermittently fails to start when coldfusion installed

Afternoon folks

 

New build of coldfusion 2025 on Ubuntu. Apache version 2.4.52.

 

On starting the apache service, I periodically get this:


Sep 17 16:01:00 intranet01.tectcorp.com systemd[1]: Starting The Apache HTTP Server...
Sep 17 16:01:00 intranet01.tectcorp.com apachectl[1813]: Segmentation fault (core dumped)
Sep 17 16:01:00 intranet01.tectcorp.com apachectl[1813]: Action 'start' failed.
Sep 17 16:01:00 intranet01.tectcorp.com apachectl[1813]: The Apache error log may have more information.
Sep 17 16:01:00 intranet01.tectcorp.com systemd[1]: apache2.service: Control process exited, code=exited, status=139/n/a
Sep 17 16:01:00 intranet01.tectcorp.com systemd[1]: apache2.service: Failed with result 'exit-code'.
Sep 17 16:01:00 intranet01.tectcorp.com systemd[1]: Failed to start The Apache HTTP Server.

 

This only happens every few times that I try to start apache. If I try to start it again after the failure, it usually starts without error. Then after a couple of times of stopping and starting the apache service, I get the error again.

 

If I take the following config out of apache2.conf:

 


Include "/etc/apache2/mod_jk.conf"
Include "/opt/coldfusion2025/config/wsconfig/1/mod_jk_vhost.conf"

 

It works 100% of the time, so coldfusion appears to be at fault. I have looked through the log files, but don't see anything that stands out as being useful. Anyone seen this before?

    I ran into this about a month ago with Ubuntu and the same Apache version. This is a bug with the mod-jk drivers that Adobe and I had to get a new mod-jk.so file from support to get it resolved. They told me they would provide the fix in the next update, but Adobe Support should be able to get you the updated .so file.

    Thank you Brian. Do you have the ticket #? I have a ticket in with support, but they seemed entirely unaware of this. I will give them your ticket # for reference.

    I don't have a ticket. I think the easiest thing is to just tell them my name and let them know I requested them to reach out to me for context (they will not find it in the ticket system).  They know how to reach me. 

    I checked my old emails, it was back in July 2025 and the fix was a replacement mod_jk.so file. It was a very difficult error to troubleshoot.

    While there may be more diagnostic info in any of various logs (apache or cf), it may prove rather simple to solve.

     

    Do you find a workers.properties file in your /opt/coldfusion2025/config/wsconfig/1/ folder? In that change the value of heartbeat_interval to 0, which disables the connector heartbeat mechanism (used only by the cf pmt, which you may not even be using to monitor this cf instance). Restart apache, which will reload and pickup the change to that file. Let us know if that helps.

     

    Or let us know if you may dig further into the various logs, to find any additional detail.

    There is no workers.properties file in that location. Not sure if there is supposed to be? I'll review the log files again and see if I missed anything the first time around.

    Found it in \etc\apache2. Making change and testing
