Hi
Thanks guys for replies.
@Matus UHLA,
Yes the mem cache is shared among the 4 squid worker processes.

There was a report about an issue and the claim was Ubuntu Kernel issue.
I believe that the first step would be to find out if a kernel downgrade or upgrade (to xenial one) helps with the issue.

Subject: Squid Memory Problems
Hi there,
We are using Squid 3.5.14 on Ubuntu 14.04 LTS. The squid is using 4 worker process and is used as an explicit and intercept proxy.
We have been facing a problem of squid processes consuming the memory gradually and eventually it comes to a minimum threshold. The end user browsing experience becomes extremely slow at that time. Cache memory configured is 2 GB and total memory of squid machines is 8 and 16 GB on different boxes. The memory consumption graphs shows a gradual decrease in available physical RAM and we have to ultimately restart the squid boxed after 3-4 days.
The stats we get from cachemgr show:
Cache information for squid:
Hits as % of all requests: 5min: 1.7%, 60min: 2.2%
Hits as % of bytes sent: 5min: 0.2%, 60min: 0.1%
Memory hits as % of hit requests: 5min: 91.7%, 60min: 82.8%
Disk hits as % of hit requests: 5min: 0.0%, 60min: 0.0%
Storage Swap size: 0 KB
Storage Swap capacity: 0.0% used, 0.0% free
Storage Mem size: 2097056 KB
Storage Mem capacity: 100.0% used, 0.0% free
Mean Object Size: 0.00 KB
We are suspecting memory leaks to be the cause of this. Please share you experiences .
Thanks
Rahat

I would like to note that squid does not use memory only for cache, but for
many different uses.
do you use shared memory cache?
