SYSTEM_NO_TASK_STORAGE while remote client copy

Former Member

Hi Gurus,

I am performing a remote client copy 600 client from Production server to 400 client in development server. I have selected SAP_ALL profile. Once I schedule the job in background within few seconds it terminates with an error "SYSTEM_NO_TASK_STORAGE"

Short text

Unable to fulfil request for 4445184 bytes of storage space.

If the error persists, ask your system administrator to check t

following profile parameters:

o ztta/roll_area (1.000.000 - 15.000.000)

Classic roll area per user and internal mode

usual amount of roll area per user and internal mode

o ztta/roll_extension (10.000.000 - 500.000.000)

Amount of memory per user in extended memory (EM)

o abap/heap_area_total (100.000.000 - 1.500.000.000)

Amount of memory (malloc) for all users of an applicatio

server. If several background processes are running on

one server, temporary bottlenecks may occur.

Of course, the amount of memory (in bytes) must also be

available on the machine (main memory or file system swa


The operating system must be set up so that there is als

enough memory for each process. Usually, the maximum add

space is too small.

Ask your hardware manufacturer or your competence center

about this.

In this case, consult your hardware vendor

abap/heap_area_dia: (10.000.000 -

Restriction of memory allocated to the heap with malloc

for each dialog process.

Parameters for background processes:

abap/heap_area_nondia: (10.000.000 -

Restriction of memory allocated to the heap with malloc

for each background process.

Other memory-relevant parameters are:

em/initial_size_MB: (35-1200)

Extended memory area from which all users of an

application server can satisfy their memory requirement.

I have checked in RZ10, all the parameters fullfills the requirements except ztta/roll_area, the parameter value for this 4000768.

Please help me out to fix this issue asap cos the matter is very urgent. Thanks for your valuable inputs.

Most likely a problem with heap memory.

Increase the size of abap/heap_area_dia, nondia, and total... and try it again.
