Re: [Gluster-devel] GlusterFS clients getting disconnected from servers with signals 6 and 11

[Matthias Saou]

Hi,

It's worth noting that both those packages are actually based on a
checkout from glusterfs--mainline--2.5--patch-628 or 636 (don't
remember for sure and "make dist" created "glusterfs-1.3.8.tar.gz"
tarballs for both), so both the server and the client are the same
version here.

The read-ahead.so segfault might have been fixed here, right? :

    Summary:
      lock read ahead conf while adding new ra_file_t in ra_open_cbk
      and ra_create_cbk - caused random memory corruption
    Revision:
      glusterfs--mainline--2.5--patch-741

The libfuse signal 6 is a bit more confusing. The client here is using
fuse 2.7.2 with the glfs8 patch if that can indicate something. It
looks memory allocation related, so maybe it's actually a consequence
of the above bug too?
