short on chunk memory..

I have just recently found polipo and have found it quite impressive.

I am trying to tune it to be a 'cache_peer' for our squid setup.

polipo being the final hop that leaves the network Internet bound..

I find that I routinely am 'short on chunk memory' regardless of what
I tune or do not tune.

I have made an elaborate monit/daemontools setup for polipo. I have
even gone so far as to make two proxies for squid to cache_peer to.

I have not seen any posts for the December 2012 year so I am not sure
if I am talking to a dead horse..

below is the basic config for both proxies:

pidFile = /var/run/polipo/polipo.pid
proxyAddress = "0.0.0.0"    # IPv4 only
allowedClients = 127.0.8.0/24, 127.0.0.1, 10.20.0.10
proxyName = "polipo.pcsd"
diskCacheRoot = ""
dnsQueryIPv6 = no
censoredHeaders = from, accept-language, x-pad, link
censorReferer = maybe
logFile=/var/log/polipo
maxAge = 5m
maxExpiresAge = 5m
maxNoModifiedAge = 5m
maxConnectionAge = 5m
clientTimeout = 92s
serverIdleTimeout = 30s

and the daemontools run file for each of the processes looks like this:
exec /usr/bin/polipo -c /etc/polipo/config
logFile=/var/log/polipo-8124 pidFile=./polipo.pid
proxyAddress=127.0.8.124 proxyPort=8124

(the other being 8125)

and the squid lines sending traffic to the polipo proxies:

cache_peer 127.0.8.124 parent 8124 0 no-query no-digest
no-netdb-exchange round-robin
cache_peer 127.0.8.125 parent 8125 0 no-query no-digest
no-netdb-exchange round-robin
# never_direct allow all

When working properly never_direct forces squid to get results from
the cache_peers..

I have monit checking the 8124/8125 is accessable, and if not, svc -t
/service/polipo[8124 8125]; which restarts it, but it still hangs..

this machine is a vm and I only have 4G allocated to the vm, but have
more if it would help.

this is another config that I was working on.. but again it still ends
up 'short on chunk memory'

pidFile = /var/run/polipo/polipo.pid
allowedClients = 127.0.0.1, 10.20.0.10
proxyName = "polipo.pcsd"
chunkHighMark = 536870912
diskCacheRoot = ""
disableServersList = false
dnsQueryIPv6 = no
dnsUseGethostbyname = yes
censoredHeaders = from, accept-language, x-pad, link
censorReferer = maybe
pmmFirstSize = 262144
pmmSize = 32768
chunkCriticalMark = 262144
chunkLowMark = 0
maxAge = 5m
maxExpiresAge = 5m
maxNoModifiedAge = 5m
objectHashTableSize = 0
publicObjectLowMark = 65535
objectHighMark = 131072
dontCacheRedirects = true
dontCacheCookies = true
maxConnectionAge = 5m
logFile=/var/log/polipo
serverMaxSlots = 8
serverSlots = 8
serverSlots1 = 8

I am unclear where I need to go to see how things are doing or how I
can further help myself without the aid of others..

Thanks for taking the time to read this.
