[gpfsug-discuss] mmfsd segfault/signal 6 on dirop.C:4548 in GPFS

serious enough that I want to make sure everyone sees it. Does anyone,
from IBM or otherwise, have any more information about this/whether it
was even announced anyplace? Thanks!<br><br>A little late, but we ran into a relatively serious problem at our site
with 5.0.2.3 at our site. The symptom is a mmfsd crash/segfault related
to fs/dirop.C:4548. We ran into this sporadically, but it was repeatable
on the problem workload. From IBM Support:<br><br>2. This is a known defect.<br>The problem has been fixed through<br>D.1073563: CTM_A_XW_FOR_DATA_IN_INODE related assert in DirLTE::lock<br>A companion fix is<br>D.1073753: Assert that the lock mode in DirLTE::lock is strong enough<br><br><br>The rep further said "It's not an APAR since it's found in internal
testing. It's an internal function at a place it should not assert but
a part of the condition as the code path is specific to the DIR_UPDATE_LOCKMODE
optimization code... The assert was meant for certain file creation code
path, but the condition wasn't set strictly for that code path that some
other code path could also run into the assert. So we cannot predict on
which node it would happen.” <br><br>The fix was setting disableAssert="dirop.C:4548, which can be done
live. Anyone seen anything else about this anyplace? The bug is fixed in
5.0.3.x and was introduced in 5.0.2.0/1 (not sure what this version number
means; I’ve seen them listed X.X.X.X.X.X, X.X.X-X.X, and others).<br><br>--<br>____<br>|| \\UTGERS,
