Issue #1395 has been updated by konrad rzentarzewski.
good news... it seems not to be related to storeconfigs. i have small function
on puppetmaster called :template_search and it seems to be locking itself and
eating all memory.
<pre>
# /var/lib/puppet/lib/puppet/parser/functions/template_search.rb
Puppet::Parser::Functions::newfunction(:template_search, :type => :rvalue, :doc
=>
"Find first existing file and run puppet template function on it. If you
want
to concatenate multiple templates try var = template_search(file1,file2) +
template_search(file3,file4) and then use var in your resources.") do |vals|
ret = nil
errors = Array.new
vals.each do |file|
debug "in :template_search find %s" % file
ret = nil
begin
ret = function_template(file)
rescue Exception=>e
if /could.not.find.template/i =~ e
debug "in :template_search not found %s" % file
else
raise Puppet::ParseError, "in :template_search
exception in %s: %s" % [file,e]
errors.push(e)
end
end
if ret
debug "in :template_search found %s" % file
break
end
end
if ret
ret
else
if errors.length > 0
raise Puppet::ParseError, "Errors from :template function:
%s" %
errors.join(", ")
else
raise Puppet::ParseError, "Could not find any files from
%s" %
vals.join(", ")
end
end
end
</pre>
in logs it hangs on:
<pre>
Dec 14 19:10:40 punch puppetmasterd[16865]: (Scope(Class[exim::backend])) in
:template_search find exim/mailser01/exim-backend.erb
</pre>
any idea why this is happening?

Bug #1395: puppet memory usage
http://projects.reductivelabs.com/issues/1395
Author: Peter Meier
Status: Accepted
Priority: Normal
Assigned to: Markus Roberts
Category: plumbing
Target version: 0.25.2
Patch: None
Affected version: 0.25.1
Keywords: memory leaks
Branch:
In a recent discussion about using puppetd with xinetd ("main
thread":http://groups.google.com/group/puppet-users/browse_thread/thread/50c94008469fc395/11687cd0a633f8f4
) it came out that there is some investigation needed on puppetd's memory
usage.
Different people noticed that running puppetd is using a lot of footprint
(links follow), while other noticed that it uses nearly none (links follow)
Notices about high memory usage:
VIRT/RES
"141m/61m":http://groups.google.com/group/puppet-users/msg/75a8bb3b6652bae6
"127m/82m":http://groups.google.com/group/puppet-users/msg/a4a43d3edd585c03 64
bit
"166m/83m":http://groups.google.com/group/puppet-users/msg/1825ed57ff84287f
"183m/96m":http://groups.google.com/group/puppet-users/msg/ecf2cd36b6e1e3a6
version 0.24.4, 64 bit
Notices about low memory usage:
"nothing
specific":http://groups.google.com/group/puppet-users/msg/aac9fade1b906bd9
version 0.24.4
"57m/46m":http://groups.google.com/group/puppet-users/msg/680b2b2760aa8890
version 0.23.1
Personally I can add another memory usage on a 32bit machine, which is rather
low: 85m virt and 69m res, running 0.24.4
Luke then
"noticed":http://groups.google.com/group/puppet-users/msg/573a76e32fba3eb0 that
we should investigate on memory usage in the near future.
Besides the memory consumption of puppetd, also the memory consumption of
puppetmaster was discussed. There Duncan Hill noticed that splitting the
fileserver off the the main puppetmaster "improved the situation
heavily":http://groups.google.com/group/puppet-users/msg/a7083b931b5c4cda ,
however he
"noticed":http://groups.google.com/group/puppet-users/msg/f68347fdb69b8496 that
the manifest puppetmaster still consumes a lot of memory.
There have been also "other reports about memory usage trashing the master and
the
client":http://groups.google.com/group/puppet-users/browse_thread/thread/26aa8025de704cc4/1c9608f58360cdbb,
however this might not be related.
Quick Summary:
We have seen different environments reporting a lot of memory usage. Most of
them seem to be 64bit machines using 0.24.4. One report about low memory usage
was a 0.23.1 version.
Personal additional assumption: And for a first glance it looks like that 64bit
machines double the memory consumption. (Take care of this assumption)
