[Gluster-devel] Gluster 3.5 (latest nightly) NFS memleak

[Giuseppe Ragusa]

Hi,
I can confirm that memory usage is perfectly normal now (about 100 MiB), having simply disabled DRC.

Many thanks,
Giuseppe

I'm reinstalling just now to start from scratch with clean logs, configuration etc.
I will report after one day of activity, but from the old system I can already confirm that I had plenty of logs containing:

0-rpc-service: DRC failed to detect duplicates


like in BZ#1008301
Many thanks for your suggestion.

Regards,
Giuseppe
