This issue was created by maloo for wangdi <di.wang@intel.com>
This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/4f1c047c-dd60-11e3-9f1e-52540035b04c.
The sub-test test_1 failed with the following error:

Instead of reverting it can we try the patch for LU-5079 - http://review.whamcloud.com/#/c/11213. It should address the problem with the LU-4578 patch
My local testing shows that running with http://review.whamcloud.com/#/c/12330/ eliminates the looping in early reply.
I've created http://review.whamcloud.com/12330 to revert this patch.
That the node us looping on early reply makes sense, since that is the main codepath that is invoking the crypto_alloc_tfm().
I think these OOMs are due to lnet+ptlrpc and not to LDLM. In the crash dumps I find there are a trivial number of locks on the MDT. But lnet_memused may be as high as 700 MB. Running replay-single 0c (one palce where we see OOMs) under trace I see that ptlrpc_send_early_reply() is being called 1000s of times a second to handle the same three OBD_PINGS:

Perhaps we should look at reverting or adjusting:
commit 8b2f9c0e40822dd847494f27d9ef4c6858fee78c
Author: Chris Horn <hornc@cray.com>
Date: Mon Feb 3 15:24:01 2014 -0600
LU-4578 ptlrpc: Early replies need to honor at_max
When determining whether an early reply can be sent the server will
calculate the new deadline based on an offset from the request
arrival time. However, when actually setting the new deadline
the server offsets the current time. This can result in deadlines
being extended more than at_max seconds past the request arrival
time. Instead, the server should offset the arrival time when updating
its request timeout.
When a client receives an early reply it doesn't know the server side
arrival time so we use the original sent time as an approximation.

Hi Andreas, I just updated the commit message to remove the 'fortestonly' parameter. Let's wait for test results.
Yu Jian, it isn't clear why you made the patch http://review.whamcloud.com/12290 to revert commit bfae5a4 fortestonly? If this fixes the problem then we would want to land this patch to master.
I agree with James that the patch for
LU-5079should resolve this issue.
