I have started getting deadlock exceptions thrown from code that uses Guavas ConcurrentHashMap
http://code.google.com/p/googleappengine/issues/detail?id=5384 Aside from this problem, loading requests frequently seem to block on something (resource access?). Normally they complete in 5-8 seconds but sometimes (~25%) they take 20 - 60 seconds or just time-out (DEEx). I was not getting either of these problems with thread-safe=false but latency was higher so I don't want to switch back to that mode. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
