Problem Note 59658: SAS® Scalable Performance Data Server shared memory segments are not cleared after server shutdown
 |  |  |  |  |
Shared memory segments are not being cleared after the SAS Scalable Performance Data Server is shut down.
Each time that the SAS SPD Server is terminated, four memory segments become unattached (value 0 in the nattch column), as shown in the following example:
$ ipcs -m ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 28082180 sasts 600 21128 0 0x00000000 28114949 sasts 600 21128 0 0x00000000 28147718 sasts 600 21128 0 0x00000000 28180487 sasts 600 21128 0 0x00000000 102891528 sasts 600 10608 4 0x00000000 102924297 sasts 600 10608 1 0x00000000 102957066 sasts 600 10608 1 0x00000000 102989835 sasts 600 10608 2 0x00000000 81199116 sasts 600 21128 0 0x00000000 81231885 sasts 600 21128 0 0x00000000 81264654 sasts 600 21128 0 0x00000000 81297423 sasts 600 21128 0
