Memory Leak

slmclarengt · Post by **slmclarengt** » Thu Jan 03, 2008 12:56 pm

In my experience in the department of programming, there is one problem I dislike probably more than any other; memory leaks! I think the latest RC beta may be bugged with a memory leak because WC3FT is the only plugin I have changed since my server started very consistently crashing, crashing some more and more...

I as well face crashes. I am working with my host to try and get core/debug.log files for crashes. Strangly, there doesn't seem to be any being created. My next step is to leave the server in the crashed state next time and get them to tell me exactly what they see on their end. Cause, not even their server console log shows any reason why it is crashing, it just terminates.

slmclarengt · Post by **slmclarengt** » Thu Jan 03, 2008 8:04 pm

Here's the end of the log file, they all end similar to this: L 01/02/2008 - 16:29:27: "-[.40 cal ]- [D]ean Wh[!]t[E] *<347><STEAM_0:0:231631

That's where it seems to cut out for all of them, at least for me; at the right carrot.

I can't think right now; probably too much COD4 for a day and helping too many people with some crappy computer builds, giving them better ideas because some just suck. So I can't even think much about it; maybe SQL related, I don't know, I don't use SQLite so I can't say if it works fine then.

I use SQLite. My normally will only crash at a mapchange. No HLDS error, but it did generate a core log file, though it is 2.4 gigs. I am going to see if Bail or someone can tell me how to look at the file or if they can. I will report back when I get something

well i know an logic index out of bounds error will terminate hlds.exe

I entirely agree that there must be memory leaks... But I have no idea how to debug this...

*technically* you shouldn't be able to create a memory leak through an amxx plugin b/c of the simplicity of pawn (no new/delete or memory management functions).

But I understand if enough amxx functions are called perhaps eventually a bug could exist in amxx which would cause a memory leak.

Not sure how to debug

I asked Bail about something last week. I had a core file that I sent to him to see if he could tell me anything about it. And I also sent him a PM requesting a debug version of the 1.8 core (he told me to). So, once I get a response back from him, I will let you guys know

Code is never so simple to prevent problems. I couldn't tell you where to debug this but maybe ensuring all functions properly terminate leaving no memory addresses open while executing prior functions. Although that is not really possible, I'd think it would be good to attempt. I think of it like Hard disks and fragments. When a program like Firefox is opening and you open a new text document. And with many programs open saving continuously to the hard disk, files become fragmented. The parts are split around the platter, which decreases efficiency. That's just how I think of functions not terminating fully; they leave "open wounds" which causes more problems, imo.

@Yami - maybe I should bother BAIL as well so my server can stop crashing and he can be quicker about helping

P.S. I doubt any of this helped at all; probably confused people, sorry
