I'm running PHP 7.2.22, with Wincache 2.0.0.8 on IIS 8.5, Windows Server 2012 R2. Everything runs well most of the time. But about every few days, Wincache stops running. PHP and everything else keeps running fine, and I only notice Wincache has stopped if I check the cache status, and see it's not storing any queries (mainly to take some load off MySQL). Then I get it going again by restarting IIS. Then it is great for a few more days.

Any ideas as to what to do to stop the error? I can set up a daily batch file to restart IIS early in the morning, but I'd rather try to solve it first, before working around it.

I see this in the error log and I see this, but it doesn't help me understand what the actual source of the problem is. I don't see any English error information anywhere.

  • You are running an obsolete version, as PHP 7.2 has reached end of life a while ago, https://www.php.net/supported-versions.php Besides, Microsoft no longer supports PHP 8.x under its own support policies, so you should seriously migrate your PHP apps away from Windows. – Lex Li Jun 24 '22 at 23:38
  • Lex, As I don't want to learn to an entire new OS and web server, I prefer to stay with Windows and therefore with PHP 7. It may be obsolete, but it works fine most of the time. The question is how to get it working without changing the entire system. I could upgrade to 7.3 or 7.4 if that's known to solve it, but I don't want to guess and find that Wincache may no longer work at all (?). – Ray Gurganus Jun 25 '22 at 00:15
  • “Supported” means an active user base around it and maintenance from the developers, so a question can never be answered if the setup is rare (but your attitude sounds like that you are well prepared). – Lex Li Jun 25 '22 at 08:30
