Error description

  • If a process or session is in a mediaW state and that process or
session is cancelled, the TSM Server may crash. The following
call stack was generated on AIX when a cancel process on a move
data was issued:

asCancelOutputMountWait@AF33_27(??, ??, ??, ??) at 0x100103ad4
asCancelOutputMountWait(??, ??) at 0x1001037e0
bfCancelMediaWaits@AF71_51(??, ??, ??) at 0x100304bf4
bfCancelMediaWaits(??, ??) at 0x1003034a4
AfMoveDataCancel(??, ??, ??) at 0x1005567dc
procCancelProcess(??, ??) at 0x1002f924c
AdmCancelProcess(??) at 0x10083f1a4
AdmCommandLocal(??, ??, ??, ??, ??) at 0x10015b220
admCommand(??, ??, ??, ??, ??) at 0x10015c07c
SmAdminCommandThread(??) at 0x1006e2c74
StartThread(??) at 0x10000fe58

Since the call stacks can vary, if the bfCancelMediaWaits is
seen, that is a good indication this APAR applies. As per above
call stack , the Cancel of MOVE DATA causes Mount Wait state to
be cancel and TSM server crashes with core dump. This problem is
caused by unsynchronized operation on some data structures
between internal threads.
