CPCA.EXE - Forbidden escape representation in URI

[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 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

Andy
