[Scst-devel] SCST crash

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi,
I'm using SCST 3.0.0.-pre2 (scst_user).
Sometimes, after creating all volumes and mappings, I try to discover the
volumes from a windows host and receive the following SCST crash (the
following lines repeat many times).
The Host report on volumes with huge sizes.
Please advice
Thanks,
Doron
