Comment 1 for bug 1241987

In innobackupex code:

    open XTRABACKUP_PID, "> $option_tmpdir/$xtrabackup_pid_file";

Could this suggests that two simultaneous runs of innobackupex will write to same tmp/xtrabackup_pid_fie
when running ibbackup ?

Which could be avoided with: --tmpdir option ?

When I tested by running 2 copies of the backup script copies of different instances at the same time I didnt have issues.

Only when the logs are being scanned as suggested by this I have the problem:

xtrabackup: using O_DIRECT
