I need a lot more detail about this issue, including a sample piece of creole text that demonstrates the problem.

You can see the bug in the euweb project, see format.e See line 173.
case Plugin then
lInstance = pParms[4]
lParms = keyvalues(pParms[1], -1, -2)
lHTMLText = ""
switch upper(lParms[1][2]) do
case "WIKIPAGE" then
--lHTMLText = creole_plugin_wikipage(lParms)
end switch
The creole_plugin_wikipage function is at line 59:
function creole_plugin_wikipage(sequence params)
sequence result = ""
sequence style = "none"
sequence page = "--INVALID-PAGE--"
integer toc_heading = 1
log:log("creole plugin running")
for i = 2 to length(params) do
switch params[i][1] do
case "style" then
style = params[i][2]
case "page" then
page = params[i][2]
case "heading" then
if find(params[i][2], { "on", "off", "hide", "0" }) then
toc_heading = 0
end if
end switch
end for
if toc_heading then
result &= sprintf("<a href=\"/wiki/view/%s.wc\">%s</a>:\n", {
page, page })
end if
result &= sprintf("<div class=\"wiki %s\">", { style })
object wikipage = wiki_db:get(page)
if atom(wikipage) then
return "<strong>INVALID PAGE</strong>"
end if
result &= format_body(wikipage[wiki_db:WIKI_TEXT])
result &= "</div>"
return result
end function
When the wiki page contains any reference to this plugin the creole_plugin_wikipage is executed endlessly. In the log I get "creole plugin running" forever, well, until I kill the process.

After further testing, this exhibits the same endless loop problem:
case Plugin then
lInstance = pParms[4]
lParms = keyvalues(pParms[1], -1, -2)
lHTMLText = ""
switch upper(lParms[1][2]) do
case "TEST" then
lHTMLText = test_plugin(lParms)
end switch
test_plugin being:
function test_plugin(sequence parms)
log:log("test plugin running")
return "test plugin"
end function
