When running archives they are continually failing with the above error and .

ANS1512E Scheduled event 'ARCH_13' failed.  Return code = 4.

Does anyone know what is causing these errors? I've checked the Tivoli website 
and adsm.org but haven't been able to solve my problem. I'm running TSM 4.1 
server on AIX with HP clients running version 4.1.2.11.

Any advice would be appreciated.
TIA
