Increasing Ram usage / Memory Leak (Scripts) - denNorske - 08.05.2017
I never really considered this to be a problem, (as I am trying my best to write clean and optimized code) - but whatever i did in my new update (and whenever there are players on) causes massive ram usage. in 24 hours it consumes about 40% of 2gb ram on a VPS. - The ram usage drops back down to 8-10% when I restart the server, and slowly increases by time and by amount of players.
Anyone who had past experiences with leaks and how to avoid it? Which code could be causing slow build-ups like this, any way to detect it, and what is not recommended doing? I read a bit on the forums, but most replies are "do not blabalbalal" and it's completely nonsense - either way made by total newbies or guys who doesn't know what a memory leak is. So I decided to put a new topic here.
(For example: do not use OnPlayerUpdate() at all. - like come on, it matters which code you got there)
and the "new update " would mean a version update consisting of several upgraded and added systems, so no way to "go back" and see what it could be.
Could "flushing" variables through a command work? Like I choose one system I'd like to try, and i flush all the variables connected to it- and check the ram usage afterwards - Can variables hold that much information?
- I guess not, as memory leaks are just invalid adressed memory that never gets furtherly processed, if I got that correctly.
Any pointers, anything I could read more about - anything that could point me in a direction here would be really useful. I am not 100% familiar on the topic yet, and I hope to be more informed by seeing your replies. I believe I am doing something wrong, but I hope to learn from it if I find what it could be.
Thank you.

It's a plugin issue because memory usage of a normal Pawn script is fixed (size of the globals + size of the stack). Using unthreaded MySQL queries may cause memory leaks if you forget to free the result (cache_delete).

If it's a plugin related issue, how come this happens? Only changes i did in regards of plugins would be the streamer (by incognito) - that by adding a few new objects (15k of them are added).
All other plugins and things in relation remains untouched, except for a new messages on IRC.

Some plugins, such as mysql, doesn't free the result cache when you use unthreaded queries (mysql_query), so it means that every time a 'select' query gets executed, results are stored in RAM but never cleared, and so on, so it keeps increasing your RAM usage.

Might often be the most simple mistakes that causes issues like this, so I'll go through and either confirm it or prove otherwise. Although I've spent some time checking this earlier, as this was my initial thought regarding the increasing ram (and especially since it increases for more players - then there's more data to load, and you keep building up memory..)
EDIT:
It can't be the mysql_query, as the calls are equal to one another. (unless I call it twice somewhere).
Potentially, how much can a query cache hold for reading? Several mb?
A gamemode reload (GMX) doesn't flush the memory, leading me to believe it could be a plugin as suggested.

I am not too familiar with Valgrind, however it seems really cool (and helpful in my case).
Re: Increasing Ram usage / Memory Leak (Scripts) - zedshadowzw - 09.05.2017
It is probably because of ur filterscripts or plugins causing the problem!
or is it just ur graphics card

If I understood your instructions correctly, I should load one plugin at a time, and see which one's causing it? Because, if one or more plugins aren't used - my gamemode wont load - and that means none of the functionality will run.
Or should I make a blank gamemode for the purpose of testing it?
Thanks for your help so far @Gamer_Z

1) indeed use a blank gamemode for each plugin (which uses the plugin functionality just as your "full" gamemode does) 2) run only that plugin and the gamemode just for the plugin which resembles your gamemode usage with valgrind 3) let a few testers join and perform the same actions (maybe use raksamp bots or something for reproducability) 4) let them leave 5) shutdown the server 6) compare to the base measurement of you 992 bytes / 62 blocks lost, this means sa-mp leaks only 992 bytes by itself. It's not uncommon for applications to do this with a set of "static / one time initialized" variables that are not RAII encapsulated / are not freed on close (because they let the OS do this and thus purposefully leak, I call this a "static leak" - one time purposeful leak, your problem is the opposite of that, a plugin or multiple plugins keep leaking memory all the time on specific actions and don't release them when needed). 7) from your full report you know that some plugins leak memory / don't clean up on exit, time to find out which ones Maybe test each plugin with a different user count / dfferent usage count (e.g. query count + free count). If a plugin really leaks memory then you will see an increase in lost bytes / blocks when using more of the plugin functions. If a plugin does not leak then you should see the same amount of lost bytes / blocks with different usage scenarios. Once you identify the leaking plugin(s) check if you are not purposefully telling the plugin to leak (from your script). If that's done then contact the author(s) of the plugin(s) with your findings and please give them a working leaking sample/script. That will help them identify the issue faster and apply a patch almost instantly compared to "hey your plugin has a memory leak". Also just out of curiosity, if you kick all the players before a gmx, does the ram usage drop significantly? Edit: Ahw denNorske you fucked up my 1337 rep         someone please reset my rep to 1337 |
And nope, kicking players doesn't free the memory. Ram always increase, and does never go down according to graphs. It's a slower growth when there are fewer players online.
And lets say this could be the MYSQL plugin, how could i test all the code I have in my gamemode? There are quite some functionality related to it, as it's a bit of it everywhere.
Also - I went through my commits and found that MySQL and Streamer are the only ones that has been Changed or added functions for. (Either added objects, or added new queries)
