OK, i just replace "ISCSI_DEF_XMIT_CMDS_MAX * 2" by 128,
"ISCSI_DEF_XMIT_CMDS_MAX" by 64, and remove null pointer dereference
from your patch, and i report about successful overcommiting "123
sessions" boundary.
Next, i will try to create as many sessions as possible at this
configuration, and rep
Yes, i accept successful logging in to 246 targets.

Hello!
About redundancy: we have distributed filesystem (IBM GPFS), on
several nodes. Each node have it's own disks directly attachet to it -
there is no shared storage. So we use GPFS replication to store two
replicas of all data. Disks of virtual machines is actually a files on
GPFS. So, to expo

No - GPFS is used at iSER target side - not on client (XEN virtualization node).
It's not the best solution, because GPFS RDMA funct

we need at least two targets per one virtual machine, for redundancy.
Each virtualization node must host at least 128 virtual machines, so
we need to increase this limit.

Thank you for reply!
192.168.15.8 is assigned to IPoIB interface.
Next is some additional information:
Interface is in connected mode on both initiator, and target nodes.
ib_iser kernel module is loaded on both nodes, tgtd is compiled with RDMA
support.
OS used on target, and initiator sides i
