We started seeing the memory issues via diffs failing to load in the last couple of days. We last saw this several months ago and we upped the resources on the VM at that time.
No new repositories or configuration changes lately. There’s a few larger PDFs (1-2 megabytes.. not huge by any means) but nothing much bigger. We prohibit diffs larger than a few megabytes as well, so thankfully nothing there, either. Thanks for the suggestions.

Hey Terry, Prefork is required for Review Board 1.7.x, but prefork works well in the later 2.0.x releases. We're using prefork ourselves. I wouldn't expect this to be a Power Pack issue. It very well could be some obscure bug in Review Board 1.7.x. How long has this been going on? Any configuration changes to the server or to Review Board recently (new repositories, for instance)? Any log entries suggesting someone's uploading a diff of an entire repository? We've seen people attempt to upload 100MB+ diffs before, which will definitely cause CPU/memory usage to spike.

There were a number of other httpd processes but they were much much smaller. I don’t know if we’re using prefork or worker in apache. Do you have a recommendation? The server has the Power Pack installed (1.1.1) The server is configured to use memcached. We rebooted the server a couple of hours ago and memcached is currently using 10.0 MB according to /admin/cache.

Hi Terry, That sounds like a lot. Is this just one out of many httpd processes doing this? Are you using prefork or worker in Apache? Often times, this kind of thing happens when Review Board is set to use local memory caches and not memcached, but that should result in all the processes ballooning up. It could also just be that there's a memory leak somewhere in the product. That has happened before, but I don't know of any in 1.7.27.

Is it normal for a httpd process on RHEL6 to use 1739m of virtual /1.3g in resident memory? What might cause a runaway httpd process?
