Random "Could not chdir to home directory".

Hi @jiucenglou

I am not an openPBS dev, but just went through the logic quickly. It seems that if you set the sandbox=PRIVATE, the openPBS would not change directory to the home directory, instead, it would change the directory to the job directory.

Maybe you can try this out.

sandbox=PRIVATE

Thank you ! I will try sandbox=PRIVATE when the error shows up again and, since the error occurs randomly, see what happens afterwards in one or two months.

sandbox=PRIVATE

I just saw the error again, and began to try sandbox=PRIVATE.

PS: (Fortunately) this time I was also running qstat -F json almost at the same time, and the command gave a corrupted json that jq refused to parse (other time jq can parse). I am wondering what could be the cause and how to diagnolize and workaround ? For example, is it possible to use qsub to ask pbs to "retry one more time" after "freezing/choking" ?
