Hi,

I am trying to get tight integration to work (MPICH 1.2.6 et SGE 6.0u6) and face 
a problem with qrsh.  Trying to debug it separately from the integration bit, I 
obtain a "poll:protocol failure in circuit setup" on the host initiating the 
qrsh (cfr. below).  On the target host, I get the following wierd messages:

Message from syslogd at lmexec-92 at Fri Jan 13 10:47:21 2006 ...
lmexec-92 kernel: Oops: 0000 [2] SMP

Message from syslogd at lmexec-92 at Fri Jan 13 10:47:21 2006 ...
lmexec-92 kernel: CR2: 0000000000000108

We use SUSE 9.0 (kernel 2.6.5-7.97-smp) on Sun V20z (bi-opteron).

Would someone have an idea on how to further debug the problem (I have tried 
using tcpdump between the submit host and the target host, as well as the 
qmaster host and the target host, to dig into communication bits, but it's 
getting complicated...)?

Thks for any help
