However, XCache must be working for it to wait the WAIT_TIMEOUT. If there wasn't a key, the mMemc->add would have been successful (XCacheBagOStuff::set always returns true). Maybe Johannes has XCache installed and working, but it doesn't have enough space to store the message cache, so it is always a miss, and his threads are constantly racing to rebuild it. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
