This was observed against slony 2.1.1

If you have a slon running with the monitor thread on it seems to leak memory.
I was able to observe this with the disorder_test where I modified
SubscribeUnderLoad to continue with the slons running after the subscription
was done.

I then watched the VMRSS of a the slon over time.  It seemed to grow at a rate
of 100k per 5 minutes.

ssinger at ssinger-laptop:~/src/slony1-engine/slony1-engine/clustertest$ while
true ;  do  grep "VmRSS" /proc/19308/status; sleep 60; done
VmRSS:        1824 kB
VmRSS:        1856 kB
VmRSS:        1880 kB
VmRSS:        1908 kB
VmRSS:        1924 kB
VmRSS:        1952 kB
VmRSS:        1972 kB
VmRSS:        2000 kB

When I restarted the slon with the monitor_thread disabled the slon didn't grow
every minute.

This investigation was prompted from an observation in the field that 2.1 was
using much more memory that 2.0.6
