Issue

• Software installed on the system, once started crashes the server with a kernel panic. Looking into what component of this software is crashing the server. This happens whenever they start the processes, and is a repeatable crash.
• RHEL6 panic in cache_alloc_refill, kernel BUG at mm/slab.c:3069
• kernel assertion BUG_ON(slabp->inuse >= cachep->num) hit involving size-32 kmem cache, and the inuse value is equal to the num value.
