Normally only the log filling up will cause a crash.

Have you restarted the server in CONSOLE mode?

Instead of starting rc.adsmserv, CD into the server directory and start it
this way:  ./dsmserv &

That way instead of dsmserv starting in QUIET mode, it will be running in
your current AIX window, and you will see the error messages it issues as it
tries to come up.

Report those back to us, they are usually helpful...
