[squid-users] Squid - Your cache is running out of filedescriptors

[Andre Bolinhas]

Hi

I'm running Squid 5.9, and sometimes I have an issue that cause a proxy 
malfunction.
I have set the max_filedescriptors to 159514 and it's works fine for a 
few hours or day, but then suddenly, Squid run out of filedescriptors.

     listening port: MyPortNameID1

Checking mgr:info inside squidclient I can see that squid only set 4096 
filedescriptors per kid instead 15951.

Can you help me to understand why Squid losses filedescriptors and don't 
start with the correct filedescriptors values set in configuration file?

Best regards
