Hi,

I have 1 head node and 4 compute nodes, Torque 2.3.1 and CentOS 5.1.

When I submit an interactive job it hangs.

How can I trace the problem?



andrzeje:boba-head ~> strace qsub -I -l nodes=2:ppn=2


execve("/usr/local/bin/qsub", ["qsub", "-I", "-l", "nodes=2:ppn=2"], [/* 35 vars */]) = 0
.
.
.
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7e8a000
write(1, "qsub: waiting for job 78.boba-he"..., 56qsub: waiting for job
78.boba-head.sinrg.local to start
) = 56
select(1024, [3], NULL, NULL, {30, 0}
