Problem:
When loading files into "ram://" server eventually became unresponsive. Server had to be restarted to regain normal operations.
Granted my intent was to cause this error condition. However, I would have expected ColdFusion to gracefully handle the issue.
Method:
Using this code to continuously write files to ram. My source was a 17mb pdf file.
<cfscript>
local.file = fileRead(expandPath('.') & '\..\PDF\Docs\czech.pdf');
for (x = 1; x < 100; x++){
local.pdfName = listLast(createUUID(), '-');
fileWrite("ram://#local.pdfName#.pdf", "#local.file#");
}
</cfscript>
Result:
http response header from server:
