I thought I would pass this along...I have two Spectrum Protect 8.1.4 instances on the same AIX 7 LPAR that since their upgrade to this version has had frequent exhausting of paging space crashes. We reviewed and checked processes and figured it was an AIX issue. Upon deeper investigation I noticed there were some previous APARs for DB2 exhausting paging space due to a 64k block size. Investigating that further led me to the following APAR for Spectrum Protect
IT23731: SPECTRUM PROTECT SERVER ON AIX MAY RUN INTO PAGING AND OUT OF MEMORY CONDITION
IT23731: SPECTRUM PROTECT SERVER ON AIX MAY RUN INTO PAGING AND OUT OF MEMORY CONDITION
So to check I ran the following shell command to list the top 10 processes using memory/paging
# svmon -Pt 10 -O summary=basic,unit=MB
Unit: MB

4849682 db2sysc 559.20 47.6 37.2 657.31
So the db2sysc and dsm2vend along with the dsmserv are using up large amounts of paging.
Here is my using in topas
PAGING SPACESo what's the solution? Restart the TSM instance(s) until you can upgrade to 8.1.5
