We have about 15 file servers with samba (version 3.05, 3.0.14 and 3.0.22) on Redhat 7.1-7.3 and FC4. Opening on it with arcview a .dwg file is fine, it creates a good temporary .iwg (some MB), like using the file on a local disk. Only in one installation (RH 7.3 updated, with kernel 2.4.20-28, samba 3.0.5 and 3.0.22) we have a problem. Arcview write always a .iwg file with a 8 byte size, and finally it crashes. Of course we did a lot of tests (disabling oplocks, kernel locks, changing file name and position, changing file and user/group permissions etc.), and we are using for comparison the same configuration on a similar hw and identical OS working server (i.e. the same testparm -v output). Does anyone have experience about this kind of problem with arcview or temporary files? Thank you in advance. Alessandro Gignoli a.gignoli@arpat.toscana.it
