What steps will reproduce the problem?

1. tar zxvf memcached-1.4.22.tar.gz cd memcached-1.4.22 ./configure make make test

meke test is not successful

What is the expected output? What do you see instead?

Finally, following error

t/lru-crawler.t ...... 93/189 Timeout.. killing the process t/lru-crawler.t ...... 96/189

・・・

Looks like you planned 189 tests but ran 188.

Looks like you failed 93 tests of 188 run.

Looks like your test exited with 111 just after 188.

I hit the same "make test' problem on Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-48-generic x86_64) and memcached-1.4.24

This is on an micro Amazon EC2 instance with 1GB memory.

Just realized that i've opened another bug for the same issue: https://code.google.com/p/memcached/issues/detail?id=417

Same problem here, Ubuntu 14.04, build (latest) from source.

For me it only fails on One CPU instance, anything with 2 or more cpu can finish the test
