Recently we have had three read/write gateways (version 2.0.4.0) crash at different times with the following error appearing in the gateway log.

PV Gateway Aborted (SIGBUS)

The crashes have all occurred when doing a caput thorough the gateway.

The server option on the gateway causes an immediate restart of the gateway however the restart doesn't seem to cure the problem with the particular PV's we are writing to although read access to all PV's is fine. Manually stopping and restarting the gateway get this back to a working state so presumably the time taken to do the restart manually is significant.

So a couple of questions:

1) Has anyone else seen this?
2) What's the best way to debug this? Presumably as its SIGBUS it has something to do with stack size or byte alignment or similar. So presumably I need to get a core dump. Is there any additional debugging in the gateway I can enable which may help?
