I see, thanks. The first problem is that tgtd can't handle the failure to create pthreads. I'll try to fix this soon. The second problem is seems that glibc has the limit of the maximum number of pthreads per process. I guess that we create too many pthreads per lun. Probably, it would be better to have some pthreads per target (regardless of the number of luns). But it takes some time to fix the second problem. -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html |
