DSOM allocates interprocess communication (IPC) resources during execution. Normally, these resources are freed and returned to the system when SOMD_Uninit is called. On AIX, however, if a DSOM process terminates without calling SOMD_Uninit, the resources often remain allocated.
DSOM offers two solutions for this problem. Either the somdclean or cleanipc command can be used, as you prefer.
