Thank you for you replies, but :-) it didn't work for me.

Hi Wodel
Randomaccess part of HPCC is probably causing this.
Perhaps set PSM env. variable -
Export PSM_MQ_REVCREQ_MAX=1000
or something like that.
Alternatively launch the job using
mpirun --mca plm ob1 --host
to avoid use of psm. Performance will probably suffer with this option
