I'm currently running 2.7.STABLE9, and don't see any FD leaking issue. It might be in your version, but not common. Please check the CacheMgr Info page, and the FD page for details on how those FDs are being used. Perhaps it will make things more clear. Our Squid has been running with the following: Started on: 31/July/2010 Clients acessing: 3,735 Avg HTTP req/sec: 12,288 Avg ICP req/sec: 16,956 Storage Swap Size: 420 GB Stroage Mem Size: 1 GB Mean Object Size: 84 KB MAX FDs used: 14,701 Current FD usage: 10,362 We run on generic hardware: Quad Core Intel 2.33 GHz with 2MB Cache Generic Intel Desktop Motherboard 1 x 80 GB IDE for OS and Logs 4 x 160 GB SATA 3.0 Gbps for Squid storage I've also just checked the File Descriptor Details page, and found as many FD listed as shown by the "Current FD Usage" on the Info page.
