Red Hat Bugzilla – Bug 1291855
When aborting due to large distribution, Erlang does not produce a crash dump
Last modified: 2016-02-18 11:10:16 EST
+++ This bug was initially created as a clone of Bug #1291822 +++
Erlang aborts in dist_port_command with ERTS_ABORT_EXIT:
if (size > (Uint) INT_MAX)
"Absurdly large distribution output data buffer "
"(%beu bytes) passed.\n",
However, ERTS_ABORT_EXIT inhibits erlang crash dump generation. It would be better to exit with ERTS_DUMP_EXIT so a crash dump is generated, in order to help debug crashes from large messages.
I will need more info. Where in openstack is erlang used and where do I find the code lines that you mention? Do you have a scenario to recreate this large buffer?
