Hello List !! We have a strange und urgent problem .... OS = solaris9 , sparc Samba = v3.0.21a , selfcompiled with gcc 3.4.3 with option "-m64" We use that server as a backupserver for xp-clients , all about 300 users, disk capacity is about 1.6 Terra Strange behaviour occured after upgrade from samba 3.0.14a 32 bit(normal) to samba 3.0.21a 64 bit. Smb.conf remained the same , also all under ./var/locks. Starting and connecting to domain didnt show any error, filetransfer bigger then 2GB no problem , all seemed well..., but in "real life" problems showed up, winbindd is dying several times a day and needs to be restarted. Also i had to disable any locking in smb.conf espacially posix locking.That seems to be a 2GB issue in solaris too. Winbind functionallity is essential for us , because access is only handled via net groupmapping from ADS, no local users in /etc/passwd. Are there any known issues with version 3.0.21a and solaris 64 bit ?. Any help or hints would be very appreciated Kind regards Martin Schreiber
