Map server crashes

[sizenine]

Since I started using rA (used 3ceam before), I've been getting map servers quite frequently:

"Crash signal was sent! Attempting to save all.."

I want to help but I'm not sure how to find out the cause of the issue. Any advice? I'm currently on r15689 so I'm pretty up to date too..

I have a feeling it's caused by skills though and I also found these leaks, but I'm not sure if that helps..

Here are the lines in my src...

clif.c line 849:

tbl = (struct block_list*)aMalloc(sizeof (struct block_list));

add_timer(tick, clif_clearunit_delayed_sub, (int)type, (intptr_t)tbl);

}

break;

UPDATE:

Some more error messages I get from the map server:

[Error]: status_change_timer: Mismatch for type 25: 126 != 2 (bl id 110015935)

[info]: Saved guild (...): members

[Error]: Server received crash signal! Attempting to save all online characters!

[info]: Saved char ....: status skills.

[info]: Saved char ....: status.

[info]: Saved char ....: inventory status skills hotkeys.

[status]: Map-server #0 has disconnected.

Segmentation fault (core dumped)

UPDATE:

I've finally pinpointed down to who's causing the crashes. For some reason I don't know why, but only a specific player's character on my server is able to crash the server with her Rune Knight. She has no equips on, no status icons on, nothing. But when she cast skills on monsters, the map server crashes after she kills a few monsters guaranteed, regardless if it was single target skill, AoE skill, or even if it was a Melee attack.

Here are some more errors we've encountered through our testing sessions with her character:

UPDATE:

I think I have pinpointed the cause... >.<

Apparently, if you have tax on a guildmember, that taxed character will crash the server when he attacks monsters.

And I bumped into some more errors:

[Error]: delete_timer error : function mismatch 0x817f210(party_send_xy_timer) != 0x80cf820(status_change_timer)

[Error]: delete_timer error : function mismatch 0x817f210(party_send_xy_timer) != 0x80cf820(status_change_timer)
