[Difx-users] FxManager: Error in launching writethread!!

[Chris.Phillips at csiro.au]

?Hi Wu


There is not enough details in your message. You should send your vex file, .v2d file. .input file and complete output from "ErrorMon" or "ErrorMon2".  Note I think ErrorMon2 filters "info" output, so the output from Errormon is probably more useful unless you know how to enable full logging with Errormon2.


Cheers

Chris

Hi all,

Recently I ran difx (2.4.1 version) and came cross the error as following:
FxManager: Error in launching writethread!!

I was using 100 cores and 4 threads each, 1 seperate header node as set in the v2d file. And the visbufferlength was set to 80. The number of stations was 3, the raw data was put in a RAID with parallel file system, while the visbility output was collected and recorded on the local disk of the header noder. Other correlation parameters was,
  tInt =0.131072
  subintNS = 8192000
  nChan = 512

I also checked the memory of the header node, the maximum occupied memory is less than 7%. So I don't know the reason of this error. Have you ever met this error before and could you please help to identify it?

Thanks a lot.

Best regards,
Wu Jiang
