[Gluster-users] Client disconnections, memory use

[Nithya Balachandran]

Hi,

For the memory increase, please capture statedumps of the process at
intervals of an hour and send it across.
https://docs.gluster.org/en/latest/Troubleshooting/statedump/ describes how
to generate a statedump for the client process.

Regards,
Nithya
