[CRIU] Can't dump task xxx running in 32 bit mode

[Federico Reghenzani]

Hi all!

CRIU is working quite well in MPI processes migration. However we have an
intermittent fault (let's say 5% of the times):

*(00.023522) Error (arch/x86/crtools.c:80): Can't dump task 1075 running in
32-bit mode*
*(00.023526) Error (cr-dump.c:1235): Can't infect (pid: 1075) with parasite*
*(00.023673) Unlock network*
*(00.023679) Unfreezing tasks into 1*
*(00.023683)     Unseizing 1074 into 1*
*(00.023705)     Unseizing 1075 into 1*
*(00.027244)     Unseizing 1076 into 1*
*(00.033880) Error (cr-dump.c:1600): Dumping FAILED.*

Please not that the task *is not* a 32 bit executable (it's a x86_64).

Any suggestion?
