There used to be a technote that no logner exists.

http://seer.support.veritas.com/docs/268122.htm :

Message Queue parameters: On some UNIX platforms with NetBackup
configurations, it can be necessary to increase the system's message
queue resources to avoid bpsched hangs.

For example, the following changes may need to be made to the
/etc/system file:
set msgsys:msginfo_msgmap=500
set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgssz=16
set msgsys:msginfo_msgseg=8192
set msgsys:msginfo_msgtql=500


Also, the below technote may be of interest.
