CPCA.EXE hangs

[AndyB]

My Managment stations CPCA.EXE hung a few days ago and required a reboot to clear it. Upon lookin at the CPCA.ELG log I notice the following type of entries dating back to middle of last year

[cpca 2240 920]@[17 Mar 16:10:50] cpca: Fri Mar 17 16:10:50 2006

cp_uri_parse: forbidden escape representation in URI (possibly layred <xx> times and times again)
collapse_path_like_ahttpd: got an 'orig_path' of length 0
cp_uri_parse: 'collapse_path_like_ahttpd' failed

http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\errors\needinit.php'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\eshop.pl\seite'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\ezadmin.cgi'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\ezboard.cgi'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\ezman.cgi'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\ezshopper\loadpage.cgi'
http_cgi_prepare_chain: the given path is not a file: '\cgi-bin\ezshopper\search.cgi'

I am not sure where this is coming from, it looks as though something/one is trying to run cgi script but at the moment cannot figure out what.

Anyone come across this before? if so is it normal or something I should be investigating further?

regards
