Hi Team,

There seems to be some problem with puppetserver.log as it is exhausting the memory in which its present with a repeated error: Too many open files

Also, there is some issue with Mcollective and ActiveMQ components, the excepts of those repeated logs are:

MCollective Log:

Are you using the latest Puppet Server release for your master - 1.0.2 for Open Source or 3.7.1 for PE? A number of file descriptor leak fixes went into the more recent releases. One trigger for the leak on older builds was the Puppet Server's inability to connect to PuppetDB to send reports.

Too many open files does not point to high memory consumption, just that the process has exceeds its number of open files limit. As this includes network connections there might be a problem here. Can you please check the following:

# strings /proc/<PID_OF_PUPPETSERVER_PROCESS>/limits
# ls -l /proc/<PID_OF_PUPPETSERVER_PROCESS>/fd/|wc -l

if both values are fairly close you may be able check with lsof -p <PID_OF_PUPPETSERVER_PROCESS> and netstat what actually makes you hit that limit.

If you share the output of the mentioned commands we might be able to help, too.
