I have a ASP.NET 4 WebAPI application (Framework 4.5) hosting in IIS 7 and monitored by Zabbix.

I noticed there are a few (0-5) peaks a day in the IIS Current Connections chart. The average current connections is 2, but suddenly it reaches a large number(300+), and drops back to 2 immediately.

Have anybody encountered such situation? What reasons do you think? Caused by C# Garbage collection? And how should I start to diagnostic?

Thanks.
