Hi,
I'm consistently getting overlaps at restore; CentOS 7.6 with Oracle 4.1.12
kernel.
Anyone have advice or workarounds?
It is consistently the same with all DMTCP versions that I've tried, including
the 2.6.1 RC:
352 dmtcp-2.6.1~rc1% env PATH=`pwd`/bin:$PATH dmtcp_launch test/dmtcp1
1 2 3 ^C
353 dmtcp-2.6.1~rc1% env PATH=`pwd`/bin:$PATH ./dmtcp_restart_script.sh
which: no dmtcp_rm_loclaunch in
(/remote/vgsource11/beatty/dmtcp/dmtcp-2.6.1~rc1/bin:<snip...>:.)
[433649] mtcp_restart.c:738 unmap_memory_areas_and_restore_vdso:
