[Valgrind-users] Fwd: unlink errors when running mysql under valgrind

[Machiel R. <mac...@gm...>]

HI all

   I am hoping this mail finds everyone well.

    I am having some issues when trying to run mysqld under valgrind.

   Due to memory leaks somewhere on mysql , we decided to run it under
valgrind in order to try and trace the problem.


     However after successfully installing valgrind on the server, we now
try to run it as follows :

valgrind --tool=massif --massif-out-file=/mnt/massif.out /usr/sbin/mysqld
--default-file=/etc/mysql/my.cnf

    however we keep getting the error :

could not unlink /mnt/vgdb-pipe-from-vgdb-to-9156-by-root-on-???


   From some research , I see that it may be because mysqld is started as
root and then changes to mysql user thus causing permissions issues

    I am however trying to find a solution to this.

   Is there anyone that can perhaps advise me as I am new to valgrind.

Regards
Mac
