Jeff, Check this link.
We had to implement this workaround. https://www.apachelounge.com/viewtopic.php?t=6037 Thanks Agnetta -----Original Message----- From: Mar Imp [mailto:marimp...@gmail.com] Sent: Thursday, August 07, 2014 4:40 AM To: users@httpd.apache.org Subject: Re: [users@httpd] Windows Apache 2.4.9 restarts itself Hi Jeff, I checked the logfiles again. There is nothing unusual there. There are no other errors logged in vhost-logfiles at the time of the restart, nothing in the Windows Event Log. What can we do? Level up the Loglevel ? At this time I have “LogLevel warn” set in httpd.conf. What do you suggest?
