Hi check this sap note this will help you to resolve this issue.
See Note 928044
The reason is behind this issue is From BW Release 7.0 onwards the BW lock server is used in BW Integrated Planning and in Business Planning and Simulation. The BW lock server uses the shared objects memory area of an application server to store the lock table. You must ensure that the size of the lock table is not exceeded during system operation otherwise terminations such as the TSV_TNEW_PAGE_ALLOC_FAILED dump will occur.
