For the past 16 months I've been reading an XML document with cffile and
parsing it into an application variable, all within an exclusive cflock
on the application scope. From there, I copied the parsed document using
duplicate() into the request scope for use throughout my application.
About three weeks ago this duplicate call began throwing errors. Since
then several other of my sites began throwing this error, all of them
are hosted at HostMySite CF+ shared hosting. The issue is intermittent,
happening for around 3-6% of the requests to the site, depending upon
which one.
The errors encountered are (and they usually appear in this order):
* The typical "null null" NPE error, java.lang.NullPointerException.
* INVALID_CHARACTER_ERR: An invalid or illegal XML character is
specified. null

I've tried replacing the XML documents to make sure they haven't become
corrupt, but despite this I've never run into any issues reading or
parsing the file, only when trying to duplicate it.
Here's the guts of the application file.
<cflock scope="APPLICATION" type="readonly" timeout="60">
<cfset request.apploaded = IsDefined('APPLICATION.apploaded')>
</cflock>
<cfif NOT request.apploaded OR isDebugMode()>
<cflock scope="APPLICATION" type="exclusive" timeout="45">
<cfif fileExists(expandPath('./themes/templates.xml'))>
<cffile action="read"
file="#expandPath('./themes/templates.xml')#" variable="xTemplate"/>
<cfset APPLICATION.templates = xmlParse(xTemplate)/>
</cfif>
<cfset APPLICATION.apploaded = TRUE>
</cflock>
</cfif>
<cflock scope="APPLICATION" type="readonly" timeout="60">
<cfset request.application = duplicate(APPLICATION)/>
</cflock>
Has anyone seen any of these issues? HMS support has not be helpful in
resolving the issue. I am forcing the application scope to rebuild
itself at this point to limit the effect of the issue, but even still
it's getting out of hand. Any help would be highly appreciated.
Thanks,
Mike
