Zone's mem growing too big

[eqwarrior]

I'm running the server on Debian and have Anguish as one of our high end raid zones. When I boot up the server for the first time, the process name zone for "./zone anguish zone" starts at 20 megs of memory, but after 2 days, its up to 1 gig of memory being used for that one zone. Is it possible there is a memory leak in one of my quest files for anguish? There are about 17 bosses in there with scripted events.

Well you're quest files don't contain the leak but the functions they call could be losing memory. I removed about a dozen leaks in the quest manager class a few months back so I know they do exist. If it is explicitly occurring in the zone with heavy quests, you've already narrowed the memory leak down to that subset.

If you are running Linux and suspect a memory leak, install valgrind, move a character to anguish and boot that zone with this script:


export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
valgrind --log-file=valglog --leak-check=full --show-reachable=yes ./zone anguish


Then run around triggering your scripts for a while, camp out and then CTRL-C the zone and you should have a text file called valglog.<processid> detailing where the memory leaks are occurring. Post it here or PM it and I'll take a look.

You don't want to do this on a 'live' server as valgrind adds a substantial overhead because of all the checking it does.

Good fixes are always nice to share! This is open source, after-all.
