TSV_TNEW_PAGE_ALLOC_FAILED dumps with http activities

[Former Member]

Hello,

SAP Release : ECC6 SP12

OS : Solaris 10

DB : Oracle 10.2

We have a memory isue that is becoming very disturbing to our end users :

It is repeting every two days :

First :

A TSV_TNEW_PAGE_ALLOC_FAILED shortdump is generated by user DDIC, while performing CCMS activities.

Client.............. 000

User................ "DDIC"

Transaction......... " "

Call Program........."SWNCCOLL"

Function Module..... "SWNC_COLLECTOR_STARTER"

The amount of storage space (in bytes) filled at termination time was:

Roll area...................... 16192

Extended memory (EM)........... 41898480

Assigned memory (HEAP)......... 0

Short area..................... " "

Paging area.................... 0

Maximum address space.......... 18446741319088363184

If the error occures in a non-modified SAP program, you may be able to

find an interim solution in an SAP Note.

If you have access to SAP Notes, carry out a search with the following

keywords:

"TSV_TNEW_PAGE_ALLOC_FAILED" " "

"SAPLHTTP_RUNTIME" or "LHTTP_RUNTIMEU25"

"WRITE_SHM_OBJECT"

Then :

More than TSV_TNEW_PAGE_ALLOC_FAILED shortdumps are generated by http users while launching webdynpros from the EP6 portal. (6 shortdumps/min)

The strange thing is that no short dump is generated from Gui users,

but only by Http users.

The amount of storage space (in bytes) filled at termination time was:

Roll area...................... 16192

Extended memory (EM)........... 4189848

Assigned memory (HEAP)......... 0

Short area..................... " "

Paging area.................... 0

Maximum address space.......... 18446741319096801552

If the error occures in a non-modified SAP program, you may be able to

find an interim solution in an SAP Note.

If you have access to SAP Notes, carry out a search with the following

keywords:

"TSV_TNEW_PAGE_ALLOC_FAILED" " "

"CL_WDR_GLOBAL_TASK============CP" or "CL_WDR_GLOBAL_TASK============CCIMP"

"UPDATE_SHM"

It is ALWAYS the SAP standard SAPMHTTP program that is involved, ...

I have opened a SAP support message they answered me to increase the size with

parameter rdisp/ROLL_MAXFS if the roll buffer has been exhausted :

But it doesn't seem to be the case in ST02 history :

Here are our others sytem parameters :

rdisp/ROLL_MAXFS : 32768

rdisp/PG_MAXFS : 150000

abap/buffersize : 500000

rdisp/PG_SHM : 8192

ztta/roll_area : 5000000

ztta/roll_extension : 2000000000

em/initial_size_MB : 4092

We have changed the parameters many times but it didn't help.

We have to restart frequently the system and for two days the system is working without short dump, until the DDIC user generate a new short dump

Any idea on how to get rid of the shortdumps ?

HI

You can check https://service.sap.com/sap/support/notes/1110822 if that helps

[former_member239282]

Hi Indus,

Check if still dumps with TSV_TNEW_PAGE_ALLOC after increasing abap/heap_area_dia, probably abap/heap_area_total has to be increased as well.

• if it helpful reward point are appreciated

Note that if your OS is solaris, you might use OSS note 324849 :

abap/heap_area_total = 0 in order to use more than 2Gb of Heap
