I found very strange behavior of FF8 and probably ff7. We have input file (see below) with ecp=read. If i start this file on a 32 windows machine i don't see any problem. Job works just fine. However, if i start the same input file on Linux (kernels 3.x and 2.6.x) i got signal 11 error. Only 64-bit linux were checked.

TID 5880 caught signal 11.

Aborting job...


On my laptop (Ubuntu 12.04LTS 3.2.0-30-generic #47-Ubuntu SMP) i also see the same error as i saw on cluster under older kernel. If i remove ecp=read keyword and adjust $drt group i can run program without any problem under different kernels. Actually, all jobs without ecp run smoothly without any problem. I tied remove $smp block, set call64=.f. , remove $p2p but no luck. Is it the bug in kernel that we discussed on this forum or it is bug(?) in ff. By the way, with ff7 i got signal 7 instead of 11. Is it something fixable?

Thank you.

Pavel.
