官网答复：
遇到的问题，是VC那台Linux虚拟机分给vsphere client服务内存资源不足的原因，和VC上管理了几台虚拟机关系不大。
您想知道vsphere client服务所需的内存大小，服务不同时刻使用资源都是不固定的，不能确定具体需求多少，我们只能通过下述操作设置分配的最大限制。
您是linux系统下的VC，就按照所发KB的 “Vcenter Server APPliance中：”下面的步骤操作即可。
执行cloudvm-ram-size -l 查看vsphere client后面的的数值大小,是现有数值大小。
再执行cloudvm-ram-size -C XXX vsphere-client XXX的值建议为上述查看值翻倍。
用ssh 登陆命令控制台.执行以下命令。
执行命令：查询当前的vsphere client 值是多少
