[squid-users] socket failure: (24) Too many open files

[Cherukuri, Naresh]

Hello Squid Group,


I am using squid 3.5.20 as a proxy server.  I Increased the memory from 12 GB to 32 GB and Max file descriptors from "4096" to "8192" and deployed this server into production on 09/26/2018".

I don't have any problem from the past 10 days everything working as expected till today. Now after 10 days for the first time, I got following errors on cache log today. Can someone advise/suggest any ideas here?
