[ https://issues.jboss.org/browse/TEIID-3106?page=com.atlassian.jira.plugin... ] Devesh Mishra commented on TEIID-3106: -------------------------------------- The issue still exists, the looping happens when we try to remove from the queue. Attaching the class with logs. LogManager.logInfo(LogConstants.CTX_BUFFER_MGR, " Thread " + Thread.currentThread() + " preparing to evict first entry, maxtofree " + maxToFree + " ,freed " + freed + " "); CacheEntry ce = queue.firstEntry(checkActiveBatch); if (ce == null) { break; } synchronized (ce) { if (!memoryEntries.containsKey(ce.getId())) { if (!checkActiveBatch) { queue.remove(ce); LogManager.logInfo(LogConstants.CTX_BUFFER_MGR, " Thread " + Thread.currentThread() + " removed from queue=" + ce.getId() + " + removed= + " + removed + " first entry " + ((queue.firstEntry(checkActiveBatch) != null) ? queue.firstEntry(checkActiveBatch).getKey() : null)); } continue; //not currently a valid eviction } } Logs are printed like ...
