multiple processes overlap

Hello

I've got a script that creates multiple processes, in ksh, to bcp out 6 tables at a time. In the script, we write messages to the log to show our progress; most of the time, the log messages are nice and neat with one per line, like they should be. But every once in awhile, at random, the messages will "overlap" each other, and I can't see why. I tried putting a sleep 1 just before we write to the log file, but the log messages still overlap.

Here is a small portion of the log file:
________________________________________________
01/07 13:37 CER_PZME_MENU_ENT..chgenv01 - bcp out started
01/07 13:37 CER_PZMG_MENU_GRP..chgenv01 - bcp out finished successfully

ES..chgenv01 - bcp out finished successfully

____________________________________________________

and here is a little bit of the code that we use. The echo statement at the bottom is what is being written to the log; I can't see why this "overlap" problem is random, and doesn't effect all the messages.
_____________________________________________________
bcp_with_error_check $dbname..$stbl out $sfile_main -$mode -b10000 -A8192 -e$sfile_error -U$suser -S$senvname -P$spass > /dev/null
# Write to the log the table date/time -- completed
sleep 1
echo `date +"%m/%d %H:%M"` $strTableName..$dbname - bcp out finished successfully
