Package: libapache2-mod-fcgid Version: 1:2.3.9-1+b1 Followup-For: Bug #779077
Dear Maintainer, In early January I upgraded from Jessie to Stretch. The server is running Sympa, which uses fcgid in Stretch for the web interface, and for Soap services. Shortly after the upgrade I encountered this bug. Researching the problem led to this report, and I determined that the bug was triggered by logrotate. I noted also that Apache only hangs if the fgci script has been accessed since last restart - ie if there are fcgi processes in memory when you attempt to reload Apache. As a workaround I modified the logrotate configuration to restart Apache if defunct processes are found after the attempted reload. This worked fine. Yesterday, however, the bug appeared again and this time logrotate was not the culprit. I investigated and determined that certbot attempts to reload Apache multiple times when renewing our certificates. I modified the letsencrypt configuration like this: [renewalparams] pre_hook = /usr/sbin/service apache2 restart By restarting Apache before certbot runs I remove fcgi processes from memory, and if there are no fcgi processes Apache reload does not hang the service. A better workaround might be to change the Apache scripts to automatically issue a restart instead of reload if any fcgi processes are in memory.
