Hi, I am running squid version 4.6 and have set the file descriptors limit to 5000 I get an average of 1 lakh hits daily and in a day or 2 , I start getting these messages : Sun Aug 18 15:00:29 2019 daemon.notice squid[4906]: WARNING: Closing client connection due to lifetime timeout

1. Should i decrease the client_lifetime ? Or should i increase the File Descriptor limit ? or adjust the timeouts
I would be looking into why these clients are having such long connection times that they hit the 1 day lifetime limit.
If they do not actually need connections open for that whole time, then lowering the client_lifetime is safe enough. You will still get these log entries, no avoiding that since the clients are holding onto connections.
You may be able to raise the FD limits as well. On a limited devices I would pair that with lowering the read_ahead_gap to 8 KB.
2. Also, there is a steady increase of memory on the device.. Squid is currently installed on an Access Point which is a resource constrained device.. Is there any way to control it..
Steadily increasing number of very log-lived client connections is likely th esource of that, each will be using up to 256KB of I/O buffers. Preventing too many connections in parallel is the best thing for that, so you are on the right track trying to remove/reduce these ones hitting the lifetime.
