NFS server RH7.1, kernel 2.4.18, client Solaris 7

Hi all,

I have the following problem,

I've upgraded to RedHat Linux 7.1 with kernel 2.4.18 (compiled with options NFSv3 server and client support checked). Clients are RH Linux 6.1, 6.2, 7.0, 7.1 and Solaris 7.
Linux clients work fine without any problem. Solaris 7 clients work fine only without locking files. If I try on Solaris to start old openwindows file manager (filemgr) it hangs for five minutes and reports just "nfs-server: RPC timed out". I think the problem is locking files. I tried on NFS server to set "insecure_locks" and "no_auth_nlm" options in /etc/exports file, but it didn`t help.

NFS server rpcinfo shows:

program verz proto port

   100000    2   tcp    111  portmapper
   100000    2   udp    111  portmapper

   100021    1   udp  32890  nlockmgr
   100021    3   udp  32890  nlockmgr
   100021    4   udp  32890  nlockmgr                  

,so lock manager is running (as rpc.statd is running).

Any idea is very appreciated.

Regards,

Sedlon
