These three messages indicate that Summary is unable to write to it's 
"Data" folder. This normally happens because of permissions problems. The 
user Summary is running as needs full read/write/execute permissions on 
Summary's Data folder and read/write permission on all of the files it 
contains. However there can be more obscure causes, see below.

Three or four people have reported this problem, but every time I work 
with someone to reproduce it, it stops happening. My best guess at this 
point is that it is related to one or more bugs in OS X, assuming you are 
running OS X.

It appears that OS X becomes unstable after it has been running for some 
time without being restarted. I suggest restarting an OS X machine at 
least weekly.

Some users have also had problems with OS X running out of vnodes, an 
internal resource in the kernel required to do almost anything. A vnode 
shortage could cause all of the problems you describe. To check for this 
problem you should run the following commands from a terminal window:

sysctl kern.maxvnodes
pstat -T

The first command, sysctl, will display the maximum number of vnodes that 
the system can currently have. The second, pstat, will display a couple 
of bits of information. The one you want is the number of vnodes 
currently in use. If the number of vnodes currently in use is anywhere 
near the maximum you are probably having a problem with vnodes.

There are several ways of increasing the maximum number of vnodes 
available, but none of them are officially supported by Apple and they 
tend to be quite complex. See for example
