[Gluster-users] Memory leak in glusterfs process

[ABHISHEK PALIWAL]

Hi Team,

I upload some valgrind logs from my gluster 5.4 setup. This is writing to
the volume every 15 minutes. I stopped glusterd and then copy away the
logs.  The test was running for some simulated days. They are zipped in
valgrind-54.zip.

Lots of info in valgrind-2730.log. Lots of possibly lost bytes in glusterfs
and even some definitely lost bytes.

==2737== 1,572,880 bytes in 1 blocks are possibly lost in loss record 391
of 391
