Brian Bockelman commented on HADOOP-4775:
-----------------------------------------
It seems that this might be memory-leak related. PS output:
root 26631 34.3 27.4 1462748 1108148 ? Ssl Dec03 426:50 fuse_dfs
-oserver=hadoop-name -oport=9000 /mnt/hadoop -oallow_other
This is a 4GB nodes, so fuse-dfs is using about 1GB of memory. Suspicious. I
haven't had much luck with GDB on the fuse_dfs process, as multithreaded apps
are tough to step through.
> FUSE crashes reliably on 0.19.0
