Likelihood evaluation failed with fault 333 ; trying with reduced updates

asreml软件报错：

Likelihood evaluation failed with fault 333 ; trying with reduced updates
Error in asreml(trait1 ~ Block/Rep, random = ~vm(ID, ainv), data = nested) :
ASReml failed to build MME (XXG); try increasing ‘workspace’.

十有八九：
看一下ainv有没有数值：

> head(ainv)
     Row Column Ainverse

说明构建逆矩阵出错。

狗血的解决方案：
重启R语言，在运行一下。

怀疑的bug：
ainverse间歇性神经！！！

另外的解决方式：

运行下面命令，查看ainv有无结果，如果有，就说嘛ainverse能用了。

library(asreml)
data("harvey")

ped = harvey.ped
head(ped)
str(ped)

ainv = ainverse(ped)
head(ainv)
str(ainv)

sessionInfo()

显示信息：
