When trying to access /admin I get a blank page. After enabling debug mode etc. I see an error message that says that Memory is exhausted (always in one of several files such as sapphire\core\model\SQLQuery.php). After increasing the memory step by step to 1 GB I suspect the problem is some severe memory leak. I can't really say what causes this. Only that it started after a Content Editor edited and moved pages around in the backend. Possibly he deleted the /home Page (because it was re-created on running /dev/build the first time after /admin had stopped working).
- There are no weird entries in the database as far as I can tell (no comment spam etc.)
- I can access other admin tabs such as /admin/assets without problem.
- The frontend works without problems.
- Silverstripe Version 2.4.5.
- I could replicate the problem by copying files and DB to a local XAMPP installation.
Any suggestions?
P.S. Plenty of people seem to have had this problem over the last 2 years. Most of them seem to have had a very low memory_limit (fixed after increasing to 64 MB). Others had 20.000 spam comments. Some just got "fixed by itself" and most never got a reply.
