zfs discuss - Apr 2009 - zfs send -R core dumps on SXCE 110

Hi.

I''m running a live upgraded (from b104) SXCE build 110 and I''m
experiencing a
core dumps sending and receiving ZFS snapshots.

I sent a replication stream of a snapshot with

# zfs send -R mypool/myfs at 20090329 | zfs recv -d anotherpool/anotherfs

and it went fine. Back then I didn''t pay attention to the fact that
@20090329
was the only snapshot existing at the moment.

When I tried to send incremental replication streams with:

# zfs send -R -I @20090329 mypool/myfs at 20090330 | zfs recv -F -d
anotherpool/anotherfs

I experienced core dumps and the error message was:

internal error: Arg list too long
Abort (core dumped)

Running pstack on the core file says:
$ pstack core

I now realize that even the first command fails if I try to send a snapshot
which depends on previous ones:

# zfs send -R mypool/myfs at 20090402 | zfs receive -d anotherpool/anotherfs
internal error: Arg list too long
Abort (core dumped)

Any hint about diagnosing what might be going on?
Thanks in advance,
Enrico

next SXCE build.

Cheers,
