Master Page File Goes Missing on Server Suddenly RRS feed

  • Question

  • User-939035612 posted

    I have a compiled ASP.Net 4.7.2 Web Forms website that I discovered to not be working today. On the server I got the error that Site.master did not exist. I had not uploaded any changes to the server in over a week and I know that I did not delete Site.master from the server. The website is precompiled. This would not be the first time that a precompiled site has returned a missing file error due to a problem compiling the site, but it would be the first time that a file has gone missing after having been properly compiled for some time.

    I am currently recompiling and redeploying the site hoping that will solve the problem, but I don't want that to happen again. What could have caused that and how can that be prevented in the future?

    Did you change the current dirrectory some way ?

    Did you verify on the server whether the file is there ?

    I just redeployed the site and it was fixed. I still don't know why the problem arose in the first place or how to keep it from happening again.

    Do you have any visibility at the hardware maintaining, or is it subcontracted somehow ?

    If you have access to it I should think to verify the consistency of the disk, as you find in the properties of the disk in Windows, in the Tools tab, with a Verify button (and naturally you will need administrator rights to use that).

    Generally speaking, when it is a big firm that treats that, it is supposed having hardware OK, and it is particularly strange several times on a long period of time, but I have to admit I see no other track.

    I presume the site runs OK when testing on your machine before deploying ?

    The server is a VPS that I have RDC access to. There have also been problems with the site's Lighthouse speed scores and trouble accessing the database when there RAM use is high.

    Hum, that needs to be taken in account ...

    I missed a session about the Cloud yesterday, waiting for the record with eager.
