[Gluster-users] Glusterfsd 2.0.7 segfault

[Krzysztof Strasburger]

Hi all,
Glusterfs 2.0.6 works on our site, but i see a lot of messages like this:
[2009-10-29 11:42:04] E [server-protocol.c:6388:server_setdents] server: fd - 1 (19488922): received a null buffer, returning EINVAL
and sometimes also a random crash of servers carrying the replicated 
namespace for unified volume, probably related to a simultaneous access 
to the same file from different nodes (not sure, but it seems to be the
reason). 
The first thing i wanted to try out, was the latest release of glusterfs,
but the server crashes immediately after start. Here is the content of log file:

My first question is, does it appear on other sites too, or am i alone with
this problem? The installation runs on linux, kernel is 2.6.31.4,
libfuse 2.8.1.
