Hi All,

 

I'm installing SAP ERP EPH5 in HA environment.

The Central Service ASCS installed successfully, however, the enque server cannot be started correctly. (message server can be started)

Here is the output of dev_eqnsrv

I have tried to increase the max_requests but the server still cannot be started.

 

Please advise what should i do to make the enque server start again.

 

Thanks,

Halu
