Answer 1

I would talk to your sys sadmin. I think the there maybe a firewall involved.

Answer 2

To whom it might be interesting.

Issue resolved.

Here is where problem was(maybe it would help authors from 2 related treads).

On shared hosting sometimes you shouldn't use 127.0.0.1. Instead, use site's IP address.

So changing

memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211

to

memcached -d -m 1024 -u root -l 123.456.789.123 -p 11211

and PHP code from

$memcache->pconnect("127.0.0.1",11211);

to

$memcache->pconnect("123.456.789.123",11211);

fixed the issue.

Thanks everyone!
