Multiply fails


#1

I tried to multiply an array by it’s transpose (code in python):

result = scidb.executeQuery("store( multiply( transpose({temp}), {temp}), {covMat})".format(temp=temp_array, covMat=covMat))
scidb.completeQuery(result.queryID)

Exception of type <type 'exceptions.Exception'> value SystemException in file: src/network/NetworkManager.cpp function: abortMessageQuery line: 860
Error id: scidb::SCIDB_SE_NETWORK::SCIDB_LE_CONNECTION_ERROR2

I’ve attached the log files, 0 is just filled with just a repeating error message

2013-02-23 20:11:52,293 [0x7f949097f700] [ERROR]: Error on processing query 1101592273943 on instance 3. Message: SystemException in file: src/network/NetworkManager.cpp functio

The error is reported on worker 4 (of 4, index = 3), but the board is now telling me I am not allowed to upload files with .log extension:
“The extension log is not allowed.”

attached log for 0

Attaching the logs didn’t appear to work, so I’ve uploaded them to Google Drive here are the links:

Can you send the schema of the matrix to us too? We will try to reproduce this.
The coordinator log was full of network error messages and unfortunately not super informative–but thanks for uploading it.

Is this SciDB 13.1?

Sorry I thought I had responded to this!

The schema is:
temp<count_centered:double NULL> [article=0:9398,9399,0,stem1=0:1223051,106,0]

I am using SciDB 12.10, I have not upgraded because I am not looking forward to migrating my data! Sorry again for the delay.
