Runtime error: RFC_VMC_COMMUNICATION_ERROR (CRM 7.0)

Post by navneetjadon » Fri Oct 07, 2011 1:38 am

Hi Experts,

We are using CRM 7.0.

We are getting dump in the CRM with the following transaction CRMD_ORDER and hence not able to do any transaction with the system.
The error details are as follows:

runtime error: RFC_VMC_COMMUNICATION_ERROR
Short Text: Error during the VM container communication between ABAP and Java
What happened ?
During the communication between JAVA and ABAP stack,an error occured in the RFC layer.

Call server return code = "-1007"


Note: we have tried the given procedure to resolve it:


"The IPC need to be activated. For this you should first check the status of the VMC with the transaction sm52. If it says, "VMC not loaded", go to transaction rz10, select the instace profile and under extended maintainence, check the parameters
vmcj/enable - This should be ON
vmcj/option/ps - Ideally should be 512M
vmcj/option/maxJavaHeap - Ideally should be 256M

restart your SAP system.
after restart, go to transaction rz10 -> goto -> Profile Values -> of a server
Double click on your instance profile, in the profile parameters window, look for the parameter vmcj/enable - the status should be on."


After doing the above suggested procedure we are not getting dump But a popUP is coming with the error (when we place any order):

CRM: SAP System Message:
Work process restarted; session terminated.


Please let me know what should we do for this issue?

Thanks

Snowy

open a case with SAP. investigate SM21 and ST22 entries. investigate dev_w** contents, search SAP notes with your findings. consider a kernel upgrade, consider a SPS upgrade.

I have posted this query in SAP before 7 days but haven't got any solution. This problem is asked in diff forums but no appropriate solution is there.

The VMC is a pain to get right.

Search SAP Notes as there a quite a few regarding the VMC. There are more parameters than the original 3 - especially to do with memory management etc.

These are the parameters we use in our CRM Production System (Note that this system is CRM 2007)

vmcj/property/vmc.cachesize 8
vmcj/option/percentageSharedClasses 12
vmcj/option/percentageCopyOnlySC 42
vmcj/option/gc/sharedWaterMark 83
vmcj/option/jit/sharedCodeCacheSize 128M
vmcj/option/ps 1180M
vmcj/enable on

Your parameters may vary depending on RAM etc.
