ST02 export import buffer high swap

[former_member284785]

Hello,

I have an issue for some times. After a restart of the instance PRD everything is OK but at a specific time the export/import buffer swap highly and don't release. A screenshots speaks better :

Have you an idea to resolve this ?

Thank you in advance !

Hi Sadiq!

Thank you for your answer.

I already increase the parameter rsdb/obj/buffersize but already swap while the free storage is OK.

I don't undestand why the buffer swap.

Thank you

I am not sure what you mean by "don't release".  The buffer counts increase over time until a restart.

The 272,143 was hit on Wednesday, but no more swaps that week.

Does this happen on all app servers?

If you have memory, you could increase buffersize more and review the results.
