是否修复了 Gridgain 集群中打开文件过多的错误？

Question

Gridgain 集群失败，出现错误“打开的文件太多”。我已经按照 GridGain 的建议设置了 ulimit 值。即 nofile --> 65536.

即使在将 nofile 增加到 65536 之后，集群仍在崩溃。有什么要检查或配置的吗？

Answer 1

这里（至少）有两种可能性。

文件描述符的数量没有增加。它可以在多个级别（系统、您的用户）进行设置，如果您在错误的地方进行设置，则不会有任何效果。你不说你是怎么做到的，所以我就把你指向这篇文章：https://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/
如果你有少量的节点和大量的caches/tables，你可能需要超过2^16个文件描述符。如果是这种情况，您需要进一步增加限制
