IT44217: MEMORY LEAK IN IBM SPECTRUM PROTECT PLUS APPLIANCE

APAR status

• Closed as program error.

Error description

• The IBM Spectrum Protect Plus appliance can progressively use up
  the host memory up to a point a reboot is needed to free up the
  memory.
  The rate the memory usage is increasing depends on the applied
  workload, the more jobs are used, the quicker the memory usage
  will raise.
  The cause is the session manager that does not close internal
  sessions once tasks are completed.
  Analysis of a dump of the virgo service when the memory is in
  high usage is needed to confirm the problem addressed in this
  APAR.

Problem conclusion

• In previous versions of IBM Spectrum Protect Plus, user sessions
  could be created internally and never released, causing a memory
  leak, which, in turn, caused IBM Spectrum Protect Plus to crash
  after all available memory was exhausted. In IBM Spectrum
  Protect Plus 10.1.15.2 and 10.1.16, these bugs where user
  sessions were not released have been fixed, thus resolving this
  session-based memory leak.
