High memory map in traffic server 6.2

[Siddharth Agarwal]

Hi,

We are seeing a high number of memory maps in the traffic server 6.2
version/ It has reached the limit allowed per process on that box.

ON ATS: 6.2
sudo cat /proc/24179/maps | wc -l | xargs echo "$(date):"
Mon Sep 19 18:33:17 UTC 2016: *65531*

sudo pmap 24179 | grep anon | wc -l
65292



On ATS 5:

sudo cat /proc/1397/maps | wc -l | xargs echo "$(date):"
Mon Sep 19 18:42:57 UTC 2016: *397*

There is a huge difference between ATS 5 and 6. All other plugins in both
the versions are same. Has there been any changes in 6.2 which explains
this high number of memory maps?

Thanks,
Siddharth
