Hello,
I'm trying to reproduce it, but unable to do so for the moment.
The servers are production.
The configuration is a high availabilty cluster with 2 nodes
Here is the server log file :
2008-03-12 07:35:05 E [afr.c:4975:afr_closedir] home-ds-afr: afrfdp is NULL, returning EBADFD
2008-03-12 07:35:05 E [afr.c:4975:afr_closedir] home-ns-afr: afrfdp is NULL, returning EBADFD
---------
got signal (11), printing backtrace
---------
