Error description

  • A Tivoli Storage Manager V6.2 server may run out of memory when
    client backup to DISK type of storage pools. The activity log
    will record messages such as :
    
    << Message number 132 not available for language AMENG >>
    
    ANR0132E tbtbl.c(5129): Memory allocation failed: object
     ResultRows, size XXX.
    
    ANR0132E imqueue.c(792): Memory allocation failed: object
     invItemChunksHeadP, size XXX.
    
    This out of memory condition may be more apparent for servers
    running in a 32-bit environment.
    
    Customer/L2 Diagnostics:
    The "show mem" output collected at regular interval will show
    an increase of memory allocation in bvutil over time.
    For example :
    
      Summary of memory allocations:
    
         609279 entries, using   17059812 bytes, from bvutil.c(1869)
          ....
         633918 entries, using   17749704 bytes, from bvutil.c(1869)
    
    TSM Versions Affected:
    Tivoli Storage Manager server v6.2 on all platforms
    
    Additional Keywords:
    zz62 memleak out of mem out-of-memory exhausted 32bit 32 bit
    

Local fix

  • Use FILE type storage pools instead of DISK to prevent leak.
