They symptom is that the process hangs forever. Its difficult to differentiate this bug and simply running out of registered memory.
The bug is hit if the pml is using the mpi_leave_pinned protocol and the btl returns an error from its send function. -Nathan ________________________________________ From: [email protected] [[email protected]] on behalf of Christopher Samuel [[email protected]] Sent: Thursday, March 01, 2012 7:58 PM To: [email protected] Subject: Re: [OMPI devel] [OMPI svn] svn:open-mpi r26077 (fwd) -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 02/03/12 02:56, Nathan Hjelm wrote: > Found a pretty nasty frag leak (and a minor one) in ob1 (see > commit below).
