Dear Sir/Madam,

Thank you for contacting Online Support.


This is most likely caused by your site having met its maximum concurrent connection limit. Shared hosting accounts are subject to the following limits:



Linux




Linux Economy - 50 Concurrent Connections

Linux Deluxe - 100 Concurrent Connections

Linux Unlimited - 200 Concurrent Connections



Windows




Windows Economy - 50 Concurrent Connections

Windows Deluxe - 100 Concurrent Connections

Windows Unlimited - 150 Concurrent Connections



MySQL connection limits from your hosting server to the MySQL server follow the same limitations as Linux Shared Hosting.



MSSQL connections are limited to 100 concurrent connections.



Larger files also cause connections to remain open longer, while your site's visitors download them. Smaller files/text lead to shorter connections. As an example, a blog with fewer readers might perform fine with an economy account and its 50 concurrent connections. However, a blog with streaming media or a higher patronage would probably need more connections.



To resolve these issues, consider upgrading to a plan with a higher concurrent connection limit.




Please let us know if we can help any other way.

Sincerely,

怎么会这样哦！iis并发数才100？？怎么我站一天才不到2千人，会同时超过这么多，而且时间这么久？怎么办哦~？！哎！！以为用gd可以好好的……

你可以进行优化下网站,或者省级空间

优化怎么优化？是优化数据库吗？

比如开启伪静态，减少数据库查询，减少插件等
