[GitHub] [incubator-brpc] vagetablechicken commented on issue #1179: TimerThread模块发生tcmalloc OOM 的coredump

不仅有consume task时出现循环链表push back OOM的问题，我们还发现了TimerThread::Task的resource pool内存增长过快导致OOM的问题。
集群20台节点，仅有一台出现Task resource pool增长过快。下图为growth profile图
虽然growth未考虑释放，但这个数值基本与rss和tcmalloc的`generic.current_allocated_bytes`相近。
而且间隔35min再采一次growth，做一下diff，可以看出30min，resource pool就涨了22GB（与上图的链路相同，todo 图链接）。
