Windows IIS（8.5.96）服务器崩溃的WordPress多站点 - PHP 5.6 wincache.dll 1.3.7.0
I'm running a WordPress multisite(4.5.3) on Windows IIS (8.5.96).
Every now and then the server crashes with a Wincache error. I have updated both PHP and Wincache components on the server. Because at the moment I have to observe the server 24/7.

服务器时不时会出现Wincache错误。 我已在服务器上更新了PHP和Wincache组件。 因为目前我必须全天候观察服务器。 p>

Not sure whether this should be an answer or an comment, but here goes.
The exception code 0xc0000005 often means a shared memory access violation. At various places you find information about adding
wincache.namesalt=0x200000
to your configuration. This is a shared memory address to store objects in.
On the other hand: I'm using the same WinCache version in my environment, but it isn't used much (shared hosting). The clients use OPCache, and with OPCache the same exception code occurs frequently. It became less when I added
opcache.mmap_base=0x20000000
to our PHP.ini configuration, but it still isn't over.
The shared memory violation does not happen with PHP 7. If you can, switch to PHP 7.
