[Samba] file locks problem??

[Francesco Samba/ML]

Hello, 

i am running Samba 2.2.3a on a Red Hat Linux 7.3 box with kernel 2.4.18-10. 

I am experiencing some problems on a particular samba share, which is 
accessed by 10 Windows 98SE clients working on a COBOL production packet by 
mapping with a G: letters this samba folder. 

Well, some times a day it happens that this packed blocks because some files 
on that samba folder remains locked; i also cannot browse this network drive 
because, when arriving to these locked files, windows explorer crash. 

By viewing samba logs i see that, i think!, the problem could be perhaps in 
a oplocks problem?

The only way to repair this problem is restarting the SMB daemon. 

Could you please help me in order to solve this problem? 

Thank you again, best regards!
