Error description

• Tivoli Storage Manager server tool dsmsanlist is used to scan
  for and list all device attached to the Fiber Channel HBAs in
  the server environment. Currently the tool does not release the
  memory after scanning a single port on the HBA. When there are
  multiple ports per HBA this can cause the tool to exceed the
  allocated memory and fail with the following error:
  *** glibc detected *** ./dsmsanlist: free(): invalid next size
  (normal): 0x0000000000508a10 ***
  
  ======= Backtrace: =========
  /lib64/libc.so.6(+0x75e66)[0x7ffff78bae66]
  /lib64/libc.so.6(+0x789b3)[0x7ffff78bd9b3]
  ./dsmsanlist(main+0x15b3)[0x402273]
  /lib64/libc.so.6(__libc_start_main+0xfd)[0x7ffff7863d5d]
