vzdump to sshfs mounts fails

[HerrWeltschaft]

hi forum,
to the pve host i mounted a 3 TB folder from a remote server via:

sshfs -o reconnect,allow_other,IdentityFile=/root/.ssh/id_rsa -p 222 backupon@78.47.xxx.xxx:/usr/home/backupon/proxmoxbackup /sshfs;

/sshfs i mounted in pve storage with vzdump ability.

i did a schedule for backups. and everything seems fine.
but backups from bigger vm's dies with this error:

Warning: unable to close filehandle GEN58 properly: Input/output error at /usr/share/perl5/PVE/VZDump/QemuServer.pm line 474.

INFO: Backup job finished with errors
job errors

i tried on console and with other mount options: umask=777 but i always fails.
is vzdump limited by size?
what does this "Warning: unable to close filehandle GEN58 properly: Input/output error at /usr/share/perl5/PVE/VZDump/QemuServer.pm line 474" mean?

any hints or tipps will be great. we cant do backups at moment

kind regards
