my cluster server abend with the following error

Abend:EIP in WS2_32.NLM at code start + 0002A78CH

Running Process [CON0:2] Process.

We have two node clusters with ISCSI target running nW65sp5 on node1,
node2 and ISCSI target. recently the server abended due to WS2_32.nlm, and
we applied the latest novell winsock patch (WSOCK6J.exe) and nw65NSS5A
patches. it resolved abend issue but create another problem with the
following error on every 1 hours or 2

NSS-3.00-5001: Pool C1/ISCSI is being deactivated.
An I/O error (21624(zlssMSAP.c[1827])) at block 0(file block 0)(ZID 0)
has compromised pool integrity

**** notes: C1 is Nodes1,C2 is Nodes2 and ISCSI is the ISCSI volume name
mount on C1

This error is related to the tcpip communication issue with the ISCSI
target. So we reverted/restore back to the previous netware Winsock which
is dated on 15 october 2005. AND we restored back the problem of
WS2_32.nlm BUT the ISCSI target seems to be working fine without

Would the NW65SP5 UPdate 1 patch (The patch kit 1 for NW65SP5) help ?

any idea ?
