Hi Avati, We've been testing Glusterfs 1.3.9 for few days. Most of the errors are not cropping up now. I got following error. I couldn't understand what dose this mean. 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.11.25:1013) 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.30.51:1018) 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.30.51:1017) 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.30.51:1016) 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.30.51:1015) 2008-05-22 09:32:19 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.30.51:1014) 2008-05-22 09:32:22 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:22 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:23 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:24 E [server-protocol.c:6040:server_protocol_interpret] server: bound_xl is null 2008-05-22 09:32:26 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.11.23:1015) 2008-05-22 09:32:27 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.11.23:1013) 2008-05-22 09:32:27 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.11.23:1012) 2008-05-22 09:32:27 E [protocol.c:271:gf_block_unserialize_transport] server: EOF from peer (172.30.11.23:1010) Also I'm facing one weird problem. If I open any file for editing in vi, after some time when I try to save it I get following error. "test.sh" WARNING: The file has been changed since reading it!!! Do you really want to write to it (y/n)? Rohan
