Dear All experts,
Everytime we restart the server (or it goes down) or Moodle services (using currently Moodle 1.6.1), some files in most courses gets randomly changed: "bytes 1 Jan 1970, 08:00 AM" (PDF, PowerPoint, Word, etc) in the size and modified sections where they are downloaded. This particular files cannot be downloaded or uploaded again (to over-write). Especially, now that we have many courses, it a super hassle to update them individually on the server.
Other specs that might help us figure out the problem:
|database||mysql||version 4.1.16 is required and you are running 4.1.20|
|php||version 4.3.0 is required and you are running 4.3.9|
We have yet to figure out the logic of how this happens, except that it could be due to a PHP problem. Would we solve the problem by updating to a higher PHP version? If so, will all the database corrupted files modification date and size go back to normal?
The files still exists it is just that some files cannot be downloaded or viewed, which are those with the following "1 Jan 1970, 08:00 AM" modification date (before restarting or downtime they had normal size and accurate modification date).
To solve this problem through a preventive measure (instead of corrective one) would be great, and if anyone out there has figured that problem out, we would be very happy.
The rest of Moodle has been great! However, this sour apple thinggy is driving us crazy
The problem is actually very urgent, because students often depend on those affected files for course notes and other course related materials.
