Hi all
I have a samba pdc(master LDAP Server) with 1 BDC(slave ldap server), the
version of Samba at PDC and BDC is samba 3.0.21c. At BDC , there are some
shares declared. The shares are used to store Fox pro files. The client uses
foxpro and opens DBF file in the share declared.
and also Roaming profiles is also used at BDC. The problem is samba hangs
frequently. Once rebooted works for some time and as then samba hangs unable
to open any fox pro files.
Almost more than 100 process are getting created.
Server Hardware Configuration (BDC)
Intel Pentium 2.4 Ghz Processor
512 MB RAM
36GB SCSI Hard disk
Intel S845WD1E Server Motherboard
Adaptec SCSI PCI
Intel on board 100Mbps NIC
is it because the samba is unable to handle foxpro, ?
I have done the backtrace of a particular smbd process
