环境说明

使用了腾讯云的免费试用的1CPU/1GB服务器，通过bin/kafka-server-start.sh config/server.properties命令启动kafka服务，出现以下错误：

OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)

问题分析

kafka启用时默认要求分配1GB的内存，由于免费服务器性能限制，出现内存分配的异常

问题解决

修改kafka-server-start.sh文件：

重启执行启动命令即可。
