Question

我们正在具有AWS的ECS服务的容器中运行Kafka经纪人。该集群由3个代理组成。我们遇到了一个问题，其中任何经纪人都会随机崩溃并出现Java致命错误，如下所示。

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007fef4a3baf9e, pid=1, tid=0x00007feb7feb7700
#
# JRE version: OpenJDK Runtime Environment (8.0_102-b14) (build 1.8.0_102-b14)
# Java VM: OpenJDK 64-Bit Server VM (25.102-b14 mixed mode linux-amd64 compressed oops)
# Problematic frame:

Here，here和here是hs_err_pid1.log的整个崩溃转储。由于Pastebin的限制，将转储分为三部分。

任何人都可以帮助我在这里找到问题。

您可以在dmesg（泊坞窗主机）中搜索日志并查找OutOfMemory？可能是您需要设置vm.max_map_count递增/更改实例大小吗？
