Buckets live forever until you destroy them. Brigades live as long as the pool they're in (normally r->pool) and automatically delete any buckets still in them when that pool cleans up The bucket allocator will allocate as much memory as is needed for the maximum amount of simultaneously-alive buckets *ever*. c->bucket_alloc is a pointer to an allocator that may live as long as the whole thread. In other words, the easiest ways to leak memory with buckets are to take a bunch of buckets out of their brigade and then forget about them, or leave them in the brigade and then forget about the brigade, in which case they'll at least get cleaned up when r->pool goes away, but that still might result in a lot of buckets simultaneously allocated before the request is done. Or you could have a filter that buffers way more stuff than it should, but that's usually a more obvious bug. > I'm purposely *not* looking at the code as I'd like to know the > intention rather than what we actually do. =) -- justin Me too. :) Does the above help? --Cliff
