bpstsinfo process take up much RAM

Hi all,

I have a Media Server AIX:

uname -a
AIX media-dr-3 1 6 00F88DD94C00

cat /usr/openv/netbackup/bin/version
NetBackup-AIX6 7.6.1

when I have some processes "bpstsinfo" that take much RAM memory resurses.

Pid      Command          Inuse      Pin     Pgsp  Virtual 64-bit Mthrd  16MB

For example, I have pid 7274722 that take up 2,5 GB.
