Hi Vijay,

It’s ongoing. I’ll let you know the new value ASAP.

FYI it’s mainly concerning 1 brick per replicate (and thus its replicate brick: brick1 on storage1 and brick 1 on storage2).
To avoid to explode my /var partition capacity, yesterday i set my brick-log-level parameter to CRITICAL -but now I know there is a big problem on several bricks..
Thanks in advance for the help and fix
