Thanks! Reset the branch in ceph.git.

You should be able to reproduce the failures without teuthology. Try
running these scripts from the ceph tree with

ms inject socket failures = 5000

in the [global] section of ceph.conf:

qa/workunits/rados/test.sh
qa/workunits/rados/test_pool_quota.sh
qa/workunits/rados/cls.sh

These resulted in osd crashes in the last rados suite run linked
earlier in the thread.
