线上跑的nginx，出现了core 文件，gdb调试，发现了
p *r->connection->pool
$6 = {d = {last = 0x2e3433383835366e <Address 0x2e3433383835366e out of bounds>, end = 0x6f7374 "", next = 0x6febb0, failed = 4}, max = 176, current = 0x6fca80, chain = 0x0, large = 0x6fec20, cleanup = 0x0, log = 0x6fcae0}
last内存地址越界.这种情况是属于系统内存耗尽导致的吗？
求大神指点思路
