RFC_VMC_COMMUNICATION_ERROR in SRM

[Former Member]

Hi Guys,

We have this scenario wherein offline stores send their shopping carts through email via XI to SRM. The problem we face is that some of the messages in SXMB_MONI end up getting stuck in a queue with a message RFC_VMC_COMMUNICATION_ERROR. The weird thing about this is that some messages don't have any problems getting processed by SRM, while the others error. We have checked the data being sent, and there seems to be no problem with that.

Any ideas how to fix this?

Regards,

Glenn

Hi Glenn,

Please look for SAP notes on this issue.

Note 946679 - RFC_VMC_COMMUNICATION_ERROR

<b>Note 946625 - VM Container deactivates itself after a while</b>

Note 946680 - DpVmcSlotAllocate: no free vm

I hope,this will help.

Hi Glenn,

Could you check if your VMC is running at al.

You can check with Transaction SM52, if the first line that appears there is vmc not loaded then you can use transaction RZ10 to change the following parameters:

vmcj/enable - ON

vmcj/option/ps - Ideally should be 512M

vmcj/option/maxJavaHeap - Ideally should be 256M

updating these values will require a system restart.

Kind Regards,

Hi Glenn

Suggest you to check the following:

1) Execute Txn BBP_CND_CHECK_CUST . Do you see any error there ?

In the results, scroll down and click on icon next to 'Simulation of Pricing with Manual Price'.

You should be able to see prices here. Do you see error in pricing here ?

2) In SE38 Txn, execute program RSVMCRT_HEALTH_CHECK. All four entries should be OK here.

If there is any problem here, suggest you to immediately contact your basis support team to check Java/ABAP components working.

Also check note 1170229 and inform Basis team, in case of problems.

Best regards

Thank you Ramki and Nishant for your replies.

Ramki,

I tried executing txn. BBP_CND_CHECK_CUST, but everything seems fine:

<i>IPC Pricing is Active</i> and clicking <i>Simulation of Pricing with Manual Price</i> displays the prices with no error messages.

Note: 1170229 does not exist

Nishant,

We tried increasing the VM of the server, but we are still getting this problem.

What we did yesterday was to send multiple shopping carts via email containing the same data. What we found was that some of the messages go through without problems, while others get stuck in the queue with the error mentioned. We concluded that this shouldn't be a data problem since some of the messages get to be processed, while others don't. Any more ideas guys?:)

Warm regards,

Glenn
