Could you also provide the main msg? like:

Core was generated by `./map-server_sql'.

Program terminated with signal 8, Arithmetic exception.

or something like that ?

[quesoph]

If the server generates it again i will post it here.

Thanks

I am missing this: glibc-2.12-1.7.el6_0.5.i686 ? in my server..

[Lighta]

Yes seem you don't have that lib but this ain't the mapcrash cause, it's just for debuginfo.

I'm still trying to figure out what may cause those segfault, also you must know that gdb ain't 100% correct, sometime line are more or less what he display.

[quesoph]

i've already updated my "glibc" just to be sure.

i haven't modify those files.. so i don't know where to start.

Thank you so much for your help.

@edit

i forgot to indicate in the first post that i have edited this:

status.c

#if REMODE
static inline unsigned short status_base_matk_min(const struct status_data* status, int lvl)
#else
static inline unsigned short status_base_matk_min(const struct status_data* status)
#endif
{
#if REMODE //Renewal MATK Formula
/* this line>> */   	 return status->int_+(status->int_/7)*(status->int_/7); //return status->int_+(status->int_/2)+(status->dex/5)+(status->luk/3)+(lvl/4);
#else //Original Min MATK Formula
	return status->int_+(status->int_/7)*(status->int_/7);
#endif
}

i guess this cause the server to crash?. or not. lol

I really dun know the matter man I'm sorry, all what I tought didn't match with dumped value and code =(.

I'd suggest to do a freshcheckout and readd your modification, are those related to DB ?

well I mean you do have something like this : db_obj_remove with data adresse=0, wich seem odd but I'm not so sure with new db systeme, my general idea is like you trying to free something wich already gone. (That's for the 2nd one)

The 1st one hmm bah bl adress ?

You must know segfault is generally that you trying to access a value from an object/structure wich not here. (access violation)

Nope dun worry this edit wont cause those crash

Thank you for your advice. i will try to use another fresh server..

another error:

[Error]: Memory manager: args of aFree 0x0xb26e5bcc is invalid pointer db.c line 1053

[quesoph]

I have already used a newly checked out server and still crash.

Maybe this is caused by the delay in skill.c

this things pop out.

[Error]: Memory manager: args of aFree 0x0xb26e5bcc is invalid pointer db.c line 1053

and when i reloadscript mapserver crashes.

Thank you for your help Lighta.
