Just trying to check this off my list. We recently updated ISPC3 to 3.1.15p3. Seems after we did this we are having issues with file permissions. We have a custom application that has a script that generates files in directories and now we are getting permission errors. I have issued chmod -R 755 /imgcache and as soon a new file is created in that directory it does not get that permissions and we get errors trying to open it from our application. Could the update have caused this?
