Error description

  • Open File handles on Storage Server are not released
causingmemory leak.
Restart IBM B2B Advanced Communications to release file handles.

When being under load testing for an extended period (2-3h) B2B
Advanced Communications 1.0.0.4_3 seem to cause the the Windows
server
that hosts the MEIG_Payload (and Non_repudiation) store to
'leak'
memory. Monitoring the server revealed the memory of the box
gradually increases and does
NOT go down even after the test has completed.

After several tests, the memory of the
box increases and causes B2BAC to throw the "STORAGE not
available/reachable error" and cause complete failure.
