Hi There... My eAthena stable server is crashing sometimes.
Here is the bt full backtrace:

CODE
(gdb) bt

    func=0x81744f6 "skill_delunitgroup") at malloc.c:360
#1  0x080eed12 in skill_delunitgroup (src=0xac8f4f70, group=0xac86dd8c)

    command=0xbfdc1fa8 "@job", message=0xbfdc1f44 "4049") at atcommand.c:1414

My atcommand.c is modified. Code around lind 1414:
CODE
    if (job == 37 ||job == 45)
        return 0;

    if (pcdb_checkid(job))
    {
        if (pc_jobchange(sd, job, upper) == 0)      <----- 1414
            clif_displaymessage(fd, msg_txt(12)); // Your job has been changed.
        else {
            clif_displaymessage(fd, msg_txt(155)); // Impossible to change your job.
            return -1;
        }


CODE
#5  0x0810e49b in is_atcommand_sub (fd=11, sd=0xac8f4f70,
    str=0xacd02208 "@job 4049", gmlvl=0) at atcommand.c:8685

Again modified
CODE
    if( log_config.gm && info->level >= log_config.gm )
        log_atcommand(sd, str);

    if( info->func(fd, sd, command, args) != 0 ) <---- 8685
    {
        sprintf(output, msg_txt(154), command); // "%s failed."
        clif_displaymessage(fd, output);
    }

CODE

    message=0xb <Address 0xb out of bounds>) at atcommand.c:8721    <----- that's just this line: "return is_atcommand_sub(fd,sd,message,gmlvl);"

    at clif.c:8114
#8  0x080808af in clif_parse (fd=11) at clif.c:11348

clif.c is modified too.
CODE
        if (sd
            || packet_db[packet_ver][cmd].func == clif_parse_WantToConnection
            || packet_db[packet_ver][cmd].func == clif_parse_debug
        )    //Only execute the function when there's an sd (except for debug/wanttoconnect packets)
            packet_db[packet_ver][cmd].func(fd, sd);   <--- 11348
    }
