Hi,

While looking into other system issues, I noticed a lot of CM TCP
connections in CLOSE_WAIT -- 260 at the moment.

Sample output:
# lsof
cm 2341 9207 pfortin 26u IPv4 364889234 0t0 TCP
prf:43695->a23-62-7-48.deploy.static.akamaitechnologies.com:http
(CLOSE_WAIT)

Sample sites:
prf:43695->a23-62-7-48.deploy.static.akamaitechnologies.com:http
prf:34937->a23-0-217-196.deploy.static.akamaitechnologies.com:http
prf:56904->a23-0-217-196.deploy.static.akamaitechnologies.com:https
prf:50877->a23-62-7-25.deploy.static.akamaitechnologies.com:http
prf:38715->server-54-230-19-219.iad12.r.cloudfront.net:https

Only seeing this on this instance of CM -- I run two; the other one is
clean.

Is this normal?

Cheers,
Pierre
