[Samba] samba is freezen when it is accessed from different computers at same time
Hi all, I just installed Samba 2.2.12 on a HPUX 11.0 (192.1.1.1) and I'm sharing nfs "samba" data on another cpu (192.1.1.8). bdf (192.1.1.1): 192.1.1.8:/dsp1/fontes 14540800 13990536 517304 96% /nfs/fontes>From a windows xp (professional) computer I can do copy, paste, etc . IfI call a cobol application, it run ok too, but when another user calls the same cobol application from another computer then the first one, both of them become frozen. After that, the process must be canceled and if you retry it, nobody can run it again. The samba web administration tool shows Active Connections, Active Shares and Open Files, like below, but no kill action clean the status. A cpu must be restarted to clean these conditions.

You can do it from several computers and they run without errors. Thanks a lot for any tip. Gerson

It is ancient code, deprecated by Samba 3 series and not maintained any more. It means that it could be a bug that it is not going to be fixed by the Samba Team.> bdf (192.1.1.1): > 192.1.1.8:/dsp1/fontes 14540800 13990536 517304 96% /nfs/fontes > >>From a windows xp (professional) computer I can do copy, paste, etc .

I can't remember exactly how it works in 2.2 and I don't have any machines with manpages and documentation from that version. But that should be the way to go.> The samba web administration tool shows Active Connections, Active > Shares and Open Files, like below, but no kill action clean the status. > A cpu must be restarted to clean these conditions. > Active Connections > PID Client IP address Date Kill > 5294 dsp000-111 172.16.0.159 Wed Jan 3 11:03:51 2007 > 5348 dsp000-149 172.16.0.198 Wed Jan 3 11:06:34 2007 > 5331 dsp000-149 172.16.0.198 Wed Jan 3 11:05:27 2007 > 4483 dsp000-001 172.16.0.14 Wed Jan 3 10:34:32 2007 > > Active Shares > Share User Group PID Client Date > fontes fontes users 5294 dsp000-111 Wed Jan 3 11:03:56 2007 > fontes fontes users 5348 dsp000-149 Wed Jan 3 11:06:34 2007 > fontes fontes users 5331 dsp000-149 Wed Jan 3 11:05:27 2007 > IPC$ smbnull smbnull 5331 dsp000-149 Wed Jan 3 11:05:27 2007 > fontes root sys 4483 dsp000-001 Wed Jan 3 10:34:42 2007 > > Open Files > PID Sharing R/W Oplock File Date > 5294 DENY_NONE RDWR EXCLUSIVE+BATCH /nfs/fontes/SPA010 Wed Jan 3 > 11:04:32 2007 > 5294 DENY_NONE RDWR EXCLUSIVE+BATCH /nfs/fontes/SPA025.idx Wed Jan 3 > 11:04:32 2007 > > This condition doesn't happen when the same application is running on a > unix environment.
