Backup frozen

[Aurel]

Hello
To perform a backup I use NFS storage.

Today I have a backup that can not be completed:
INFO: status: 99% (408243535872/412316860416), sparse 93% (386627416064), duration 12760, 35/0 MB/s

INFO: status: 100% (412316860416/412316860416), sparse 94% (390700732416), duration 12888, 31/0 MB/s
INFO: transferred 412316 MB in 12888 seconds (31 MB/s)​

I checked several things:
1) nfs storage (no problem I can write, list, delete, etc.)
2) network no problem
Then I try to stop the current backup but not:
#vzdump -stop
#stoping failed backup process 738,699

All other backups no longer work because of it
Could you help me
Greating

Then i have new results of my investigation

so when i do
# ps aux | grep vzdump
#root 738698 0.0 0.0 204976 38048 ? S Dec23 1:32 /usr/bin/perl -w -T /usr/bin/vzdump

I do a strace on process and i have this result in loop

select(8, [6], NULL, NULL, {1, 0}) = 0 (Timeout)
open("/proc/738699/stat", O_RDONLY) = 10
ioctl(10, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fff98f18b60) = -1 ENOTTY (Inappropriate ioctl for device)
lseek(10, 0, SEEK_CUR) = 0
fstat(10, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
fcntl(10, F_SETFD, FD_CLOEXEC) = 0
read(10, "738699 (task UPIDroxn) S 73869"..., 8192) = 309
close(10) = 0
select(8, [6], NULL, NULL, {1, 0}) = 0 (Timeout)
open("/proc/738699/stat", O_RDONLY) = 10

lseek(10, 0, SEEK_CUR) = 0
fstat(10, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0

so i kill -9 process but i can't kill this one :

root 738699 0.0 0.0 205860 37368 ? Ds Dec23 0:26 task UPID proxnode01:000B458B:4BF5528E:567B206A:vzdump
