Date Thu, 17 Jan 2013 06:42:23 GMT

Radhika Nair commented on CLOUDSTACK-295:
-----------------------------------------

description from 296:

If the system has a lot of resources to logon to, the cloud user may run out of file descriptor
limits. If so, add the following to the limits.conf file. 
  
# set max file descriptors for cloud user to 4096 
sed -i /"cloud hard nofile"/d /etc/security/limits.conf sed -i /"cloud soft nofile"/d /etc/security/limits.conf
echo "cloud hard nofile 4096" >> /etc/security/limits.conf echo "cloud soft nofile 4096"
>> /etc/security/limits.conf rm - rf %{_localstatedir}/cache/%{name}

> Changing config files was deemed too unsavory to be done in a automated manner so that
was removed from the spec file. 
> Thus we need to add a section to installation documents that discusses modifying /etc/security/limits.conf
> Here is what was in the spec file, this should only be for the management server. 
> # set max file descriptors for cloud user to 4096 sed -i /"cloud hard nofile"/d
> /etc/security/limits.conf sed -i /"cloud soft nofile"/d /etc/security/limits.conf
> echo "cloud hard nofile 4096" >> /etc/security/limits.conf echo "cloud soft
> nofile 4096" >> /etc/security/limits.conf rm -
> rf %{_localstatedir}/cache/%{name}
