SGE: Jobs stuck in qw state

Question

I'm trying to submit jobs to SGE. It has been working for me the same way in the past. Now instead, all jobs are stuck in the qw state.

"qstat -g c" output:

> CLUSTER QUEUE   CQLOAD   USED  AVAIL  TOTAL
> all.q           0.38      0    160   1920   
> gpu6.q          -NA-      0      0      4    
> par6.q          0.38    750    135   1800      
> seq6.q          0.41    103    170    416   
> smp3.q          1.01      0      0     96  

"qstat" output looks like always.

Googling only gave me hints for people with root access which I don't have. Suggestions anyone?

Thanks.

Edit: Jobs were submitted via "qsub -q seq6.q scriptname" or alternatively smp3.q or par6.q.

"qstat -j jobid" gives nothing special as far as I can see:

I have had the same issue today. We are running Univa Grid Engine for a customer. I configured some complexes for running jobs which are requesting much memory ( h_stack=64M, memory_free=4G,virtual_free=4G) on the masterhost. After this config jobs will hang in the waiting queue. This configuration match many years with 3G on all our execution hosts. I will test this new config (4G) next days. All servers have enough memory! Ingo
