I/O Error

Hi,

Our ECC Production system with 6 APP servers are throwing continous dumps like -

CALL_FUNCTION_SEND_ERROR

"CPIC-CALL: 'ThCMSEND' : cmRc=18 thRc=0#Statistics not active "

An error occurred when executing a Remote Function Call.

There was a background job which was doing a parallel processing on all the 6 APP servers which resulted the dumps & the parallel processing error

Please let me know your suggestions for these types of errors

Thanks,

Sameer

Hi,

Check which RFC is involved in this and try to check it manually.

Provide the entire error details of the RFC connection result.

Hi Venkata,

I checked the RFCs for all APP servers and they are all fine.

Do you think this type of dump may be due to a network error? Not sure though

Hi,

Yes.. It might be one of the reason

Please check the number of dialog work processes if it is very low, which

could cause an RFC problem since RFC-calls are using dialog Wps.

At least 50% of all work processes has to be configured as dialog wp.

(Always in all systems!) This means you have to increase the number

of dialog wps to at least 18.

For more information please read the following note:

39412-How many work processes to configure

Pease increase also the parameter gw/conn_disconnect and check if the

problem still happens afterwards.

There are 72 DIA processes for 6 APP servers & the parallel processing is done using them.

gw/conn_disconnect = 900

This started from today. Earlier the jobs never gave any problems and though they occupied the DIA processes in paralel processing, it never gave dumps or errors like that.

Can I re-run the job again to see if it works?

Thanks,

Hi,

Yes.. Please try to rerun the job.
