---------------------------------------------
currently this deadlock appears frequently when we start a tomcat under heavy
load (let me guess in 95% of the time the deadlock occurs in 5% T5 starts
correctly). Am I right, that the error occurs because the pages/components byte
code manipulation is defered to first access of a particular page to minimize
the startup time? If so what about just initializing all pages/components while
starting up? ok, the startup time will increase but for production it plays no
role if startup takes 30 sec or 5 min, right? this will be different for
development I know, but when starting a TC locally there will be no heavy load
so chances to get trapped by this error should be considerably low. Furthermore
if T5 initializes all pages we will catch page errors immediately on startup
instead of finding them "accidentally when clicking through the app" (but this
is a different topic). Nevertheless I fear the frameset problem mentioned
before by Jun Tsai is different from our's
