Error: Performed cache operation with stopped CacheGroup thread

[PH]

Hi all,

we are running SAP BW 7.0 SPS 22 with an Enterprise Portal used for reporting.

We sporadically face the following issue. When I call the logon URL of the portal (http://<hostname>.<domain>:<port>/irj/portal) the logon screen appears.

After entering username and password the following error is shown:

The error only occurs for some users (e. g. my one). The error does not occur, if I use a different client machine (e. g. a PC from a colleague).

We are using Internet Explorer 8.

Has anyone of you came along the same issue?

Hello Philipp,

Please check note 1039506 - Unexpected security session expiration at a remote client

Hi Kamil,

I already checked that note and also the solution described therein. Our settings were already correct.

Meanwhile, the error has disappeared - for whatever reason

Regards,

Philipp
