[Xymon] inode test fails after change in showgraph

Hello,

Yesterday Xymon server, version 4.3.12, stopped performing the test inode, 
after a change in program showgraph.cgi.

In all Xymon pages, we show the date in an ISO8601 format. File showgraph.c 
is modified to generate an ISO8601 date too, by changing the format in the 
invocations of strftime. After a `make`, a `make install` and a restart of 
xymon server, the dates in the graphs were changed to the desired format. 
However, after half an hour, all inode tests became purple. It was found that:
  - in subdir ~xymon/server/bin only programs showgraph.cgi and xymond_rrd 
are rebuild, all the other programs have modification time multiple months 
back;
  - there are no inode-related (error)messages in any of the logfiles in 
/var/log/xymon
  - `make install` has changed some of the *.cfg files in 
~xymon/server/etc. Those changes are reverted, by reloading the previous 
version of those files from an svn repository. This had no effect on the 
colour of the inode tests;
  - defining the INODE tag in ~xymon/server/etc/analysis.cfg for one of the 
affected hosts does not change the colour of the inode-test of that host. 
The colour of the test stays purple;
  - reloading programs showgraph.cgi and xymon_rrd from a back-up does not 
change the colour of the inode-tests either. Of course the dates in the 
graphs are now again shown using the original format.

Xymon server has been stopped and started at each change. The configuration 
of the xymon clients has not been changed while looking for a solution for 
this problem.

Does any one knows how to solve this problem?
Are there more things I can do (check,restore) to get the inode test 
operational again?

Regards,
   Wim Nelis.
