Symptoms

*  In a customers production box, core dumps were frequently observed and the pipeline framework would go down printing the following message(s) on the console :

Attempt to exit due to signal caught: SIGBUS
or
Assertion failed: sizeclass < SIZE_CLASSES, file hoardheap.h, line 395

*  Customer would process the below semaphores for call assembling module and the core dump would happen :

ifw.Pipelines.GSM.Functions.Processing1.FunctionPool.CallAssembling.Module.FlushLimit=1
ifw.Pipelines.GSM.Functions.Processing1.FunctionPool.CallAssembling.Module.KeepCallOpen = True


*  Even otherwise, core dump would happen while rating CDRs in production, especially while running billing in parallel, leading to some locks on the balance groups.
*  Two sample stack trace files are attached, one for the core from Dat_BalanceBatch module and another from call_assembling module, for reference.
