Facing error "not enough memory available" even though enough heap memory available

Can you please provide an update?

Hi,

I already checked by using obj_clear for MR and instantaneous profile object and cl_clear before disconnecting as below,

16ret = cosem_init(&gMRICDataObj.base, DLMS_OBJECT_TYPE_DATA,
MR_INVOCATION_COUNTER_OBISCODE);

i16ret = cosem_init(&gInstantaneousProfileGenericObj.base,
DLMS_OBJECT_TYPE_PROFILE_GENERIC,
INSTANTANEOUS_PROFILE_OBISCODE);
cl_init(&cCon.settings, LOGICALNAMEREFERENCING, CLIENTADDRESS_PC,
SERVERADDRESS, DLMS_AUTHENTICATION_NONE, NULL,
DLMS_INTERFACE_TYPE_WRAPPER);
com_initializeConnection(&cCon);

com_read(&cCon, &gMRICDataObj.base,2);

com_disconnect(&cCon);

cl_init(&cCon.settings, LOGICALNAMEREFERENCING, CLIENTADDRESS_MR,
SERVERADDRESS, DLMS_AUTHENTICATION_LOW, HPL_MR_PASSWORD,
DLMS_INTERFACE_TYPE_WRAPPER);

cCon.settings.cipher.invocationCounter = (gMRICDataObj.value.ulVal+ 1);
cCon.settings.cipher.security = DLMS_SECURITY_ENCRYPTION;

com_initializeConnection(&cCon);

com_read(&cCon,&gInstantaneousProfileGenericObj.base,3);

obj_clear(&gMRICDataObj.base);
obj_clear(&gInstantaneousProfileGenericObj.base);
obj_clearProfileGenericBuffer(&gInstantaneousProfileGenericObj.buffer);
obj_clearProfileGenericCaptureObjects(&gInstantaneousProfileGenericObj.captureObjects);
cl_clear(&cCon.settings);
com_disconnect(&cCon);

also check that heap memory does not increase after Ip read operation.

I have enough heap memory but still gate error as "not enough memory"

Please check if anything is missing because of that I am facing this error.

Thanks,

Hi,

Need to send log file.

can you tell me how I can attach log file here?

Thanks,
Suketa

Hi,

Thanks for reply.
Here I send URI for my logs.
Logs contain Hex print, other require logs and iteration count.
After 7 successful iteration facing same issue in 8th one.

Hi,

Please find block cipher and authentication key below,

Block Cipher Key: 2222222222222222
Authentication Key: 2222222222222222

Hi,

I read invocation counter using PC so I think authentication is not requiring.

if I disconnect after read association view, same issue happened.

also, I clear the read association view object after read. you can check term "sMACStatistics.heap.uordblks" in my logs which i sent you. this term indicated used heap. and term "sMACStatistics.heap.arena" that indicate available heap.

you can see that heap is not increasing at that much level that cause problem and enough free heap available when this issue produced

Please tell me if I am missing anything in flow.

Thanks,

Hi,

I have checked after adding disconnect, same issue generated.

This error given by DLMS lib when try to establish secured connection.

Please check below logs,

Hi,

I observed that sometimes this error is coming from,

cl_aarqRequest -> bb_capacity , when try to establish secure connection.

sometimes this issue observed when trying to read IP data

Thanks,

Hi,

As you can see in my code that I previously shared with you, I clear all capture objects.

I also shared logs with you that contains log related to heap memory. you can see that no heap memory increased after IP read.

Thanks,
Suketa

Hi,

I attached my code at below link.

Please verify if any step is missing.

Hi Mikko,

I am facing same issue after this change also.
