If you don't remove the cache between versions I have seen weird behavior on trying to get locks for reading from cache: perf top output: {code} Samples: 379K of event 'cycles', Event count (approx.): 159277054084 20.54% libpthread-2.12.so [.] pthread_mutex_trylock 10.59% traffic_server [.] CacheVC::openReadStartHead(int, Event*) 5.49% traffic_server [.] MutexTryLock::MutexTryLock(ProxyMutex*, EThread*) 3.39% libtsutil.so.3 [.] ink_freelist_new 3.17% traffic_server [.] EThread::process_event(Event*, int) 3.06% [kernel] [k] _spin_lock_bh 2.56% libtsutil.so.3 [.] ink_freelist_free 1.48% [kernel] [k] _spin_lock 1.46% traffic_server [.] EThread::execute() 1.44% libpthread-2.12.so [.] pthread_mutex_unlock 1.33% [kernel] [k] copy_user_generic_string 1.22% traffic_server [.] Ptr<ProxyMutex>::operator=(ProxyMutex*) {code} -- This message is automatically generated by JIRA.
