I have a dex x64 on a virtualbox win7pro host. My apache2 will stop responding after a page request or other activity such as upload via ftp. The php.cgi becomes non responsive and a restart is required any help tracking down the culprit sending the SIGTERM would be much appreciated. thx Art
my apache2.conf has
<IfModule mpm_prefork_module>
ServerLimit 1024
StartServers 10
MinSpareServers 10
MaxSpareServers 20
MaxClients 1024
MaxRequestsPerChild 0
</IfModule> `
From the apache2 log I have
[Wed Jun 20 05:07:01 2012] [notice] caught SIGTERM, shutting down
[Wed Jun 20 05:07:03 2012] [notice] FastCGI: process manager initialized (pid 4369)

and from the accounting output with lastcomm
