Closed as program error.
Error description
A memory leak can be seen on server instances acting as library clients, and also seen on storage agents. The memory leak occurs when the library client or storage agent polls the library manager for information about shared libraries and drives. The amount of memory allocated by the library client or storage agent during polling will vary depending on the number of shared libraries/drives returned by the library manager server. The output from the "SHOW ALLOC" command will show a gradual increase in the number of memory allocation requests and the count of allocated bytes associated with the smQuerySharedLibrary() routine, as seen in the following example: smlshare.c line 702: 22470 entries for 1617840 bytes (smQuerySharedLibrary) thread 1(main parent=0) smlshare.c line 736: 2157120 entries for 655764480 bytes (smQuerySharedLibrary) thread 1(main parent=0) Over a period of time, this memory leak will cause server memory usage to slowly grow indefinitely. Note: This is a different memory leak condition than described in APARs IT24208 and IT21624. Initial Impact: Low IBM Spectrum Protect versions affected: Library client servers and storage agents 7.1.x and 8.1.x on all supported platforms Keywords: TSM TS001809561 memory leak memleak
Local fix
Restart library client server or storage agent as and when needed.
