tidyverse falha periodicamente no RHEL

Question

Nós temos um programa python que executa o R Script. Estamos usando o Anaconda versão 3.4 em um sistema RHEL 7.5. Nós usamos ambientes conda. Eu construí um especificamente para o trabalho. Tudo funciona por alguns dias e depois temos falhas. Aqui está o rastreamento de pilha:

Error: package or namespace load failed for ‘tidyverse’ in dyn.load(file, DLLpath = DLLpath, ...):

In addition: Warning message:
In install.packages(package, repos = "http://cran.us.r-project.org") :

ERROR: FAILED EXECUTION

Se eu excluir o ambiente conda r-prod-34 e recriá-lo, a tarefa será executada por alguns dias e, em seguida, ocorrerá o mesmo erro.

Não tenho certeza se isso é um problema do RHEL ou Anaconda?
