Hallo

I have a problem to understand following error:

[2013-07-16 15:36:05.056955] D [afr-lk-common.c:403:transaction_lk_op] 0-gv0-replicate-0: lk op is for a transaction

   2010         }

my suggestion:
- l2009 gf_log printed: remote operation failed: Value too large for defined data type
- according to [1]: The symbolic name for this error is EOVERFLOW, errno=79
- l2006 out: can jumping from 1986,1994 (ENOTCONN,EINVAL)
  I do not see EOVERFLOW.


where EOVERFLOW setting?
