I have a somewhat similar case here, samba processses are unkillable, but I can do a software reboot. Something is also killing amandad, and I lost the backup of this machine last night. The amanda logs are bereft of any info and I've no clue that its happened except a message from amanda that the client access timed out on this machine. This was while running 2.6.10-rc3-mm1-V0.33-04 which ran stably for 8 days previously.
