samba 2.0.7 + Linux 2.2.18

[Artur]

Hi !
Does anybody have above configuration ? I have some problems with kernel
2.2.18 and samba 2.0.7.
When people try to connect to samba server from winNT, everything is
fine, but in case of windows
95/98 it is not. There are strange log entries in the logfile:

[2000/12/19 08:54:33, 0] locking/shmem_sysv.c:sysv_shm_open(667)
  Can't create or use IPC area. Error was File exists

and etc.

Some advisories ?

Thanks
