Hi,

By unprocessed requests you mean unprocessed unexpected messages, job, bmi 
and/or trove requests ? 
I think unprocessed unexp messages shoudn't be processed, the client will 
restart them once the server is back up. Maybe it is useful to finish all 
queued trove requests to ensure metadata consistency ? Due to the internal 
ordering of the trove operations within a sm this should be guaranteed 
somehow even by discarding unprocessed elements ?

Is there a way to intercept the segfault or bus error ?
I thought we couldn't do anything at this point.

Thanks for helping me out,
Julian
