Yes, there is a respwan script, but for current practice, I would rather to let if fail early to be noticed.
So that I can identify all failures and fix them asap.
As the current server has only 1 GB memory, I will shut down the search program in a few seconds temporally, and resume it after I finish compiling the js code which consumes a lot memory.
because for the stats page, I have made some UI modifications.
Now one could take this opportunity to see what the chat room link on server fault looks like :-)
I am compiling stats page now. The modern js/webpack build is so ridiculously time consuming.
