CX_SHM_OUT_OF_MEMORY dump error in Solution Manager 7.1

Question

Hello all,
We are facing an error while executing background jobs and few other operations.When i noticed in ST22, the no of dump errors are very high.
All the dump errors are relating to SYSTEM_NO_SHM_MEMORY
I went through SAP Note 1232973 and applied the 2nd option i.e increased the parameter "abap/shared_objects_size_MB" to 300.
But no luck,the dump error keeps appearing.
Also i added a profile parameter ztta/roll_first =1, then also it keep appearing.
OS Version is AIX 5.3 64 bit
The info from ST22 is,
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SHM_OUT_OF_MEMORY', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
One of the following three possibilities has occurred:
1. There is not enough free memory available in the shared object memory
   to store further data.
2. The maximum size for a version of this area specified in the area
   administration will be exceeded in this version if more data is
   stored.
3. The maximum size for all versions of all instances of this area
   specified in the area administration will be exceeded if more data
   is stored.
The data object was to be stored in the following area instance:
"\AREA=CL_LMDB_MODEL_SHM_AREA\INST=LDB:0000000001\CLNT=\USER=0\EMOD=256".
Size of (to be created) Version .. 0
Maximum Size of Version .......... "<no or unknown bound>"
Shared Objects Memory in Total:
    Amount Used ......................... 35738256
    Amount Allocated..................... 78663680
    Free Memory ......................... 0
The size of the Shared Objects Memory is specified by the profil
parameter abap/shared_objects_size_MB.
Note: Generally, termination does not take place as soon as a memory
limit is exceeded. It happens later, at a later ABAP statement, which
may have nothing to do with Shared Objects.
Kindly suggest.
Thank You,
Regards,
Hasan

Hi,
It looks like value of parameter abap/shared_objects_size_MB is still very less. Please increase value of this parameter to some higher value and then check.
Thanks
