我也遇到了，内存只升不降导致内存泄漏，然后网络就蹦了，必须重新运行就好了，但过一会一样的情况，我目前退到409版本了

BH4WHN commented 4 years ago

确实存在该问题

cool168 commented 4 years ago

0409版本在docker里用也是内存不停的涨，我已经退回到0201版本了。

0201确定没这个问题吗？

lovexiaofan123 commented 4 years ago

0409版本在docker里用也是内存不停的涨，我已经退回到0201版本了。

还真是，0409也有这问题，只不过情况要比071要好得多，运行了1天左右才蹦掉

建议把datashard和parityshard改成10和5，0701我用了半个月了，客户端服务端都没有出现你描述的情况
