NFS server

hi, i am having problems with NFS server version 3 on RHEL4 (Nahant) unfortunately google failed to answer. nfs exports images folders in (rw) to solaris10 which run a SunOne7 Java webserver. when opening a site from the SunOne7 Java webserver i cant see the images. when trying to "ls" the file on the solaris10 server i get sometimes permission denied and sometimes file or directory cant be found, though if i "cd" to the parent directory and then cd to that file directory i will see the file by pressing "TAB" button but cant "ls" it. only when going to the NFS server machine and initiating an "ls" command to one of the images files that i cant see all of the rest of the images in that page can be seen after refreshing the page. i have enabled the following debug log command to search for any NFS errors. echo 32767 > /proc/sys/sunrpc/nfsd_debug echo 32767 > /proc/sys/sunrpc/nfs_debug echo 32767 > /proc/sys/sunrpc/rpc_debug but unfortunatlly i didnt see any errors. please note that i had a tomcat website on the NFS server that hold the same images and the same thing happens so its not related to the client side as far as i understand. i have also increased the open files in the machines. when running the follwoing command i am getting the follwoing nfs packages that installed. -bash-3.00# rpm -qa | grep nfs nfs-utils-lib-1.0.6-8 nfs-utils-1.0.6-80.EL4 These are the Solaris10 errors i get Feb 3 10:36:34 si nfs: [ID 333984 kern.notice] NFS server nati not responding still trying Feb 3 10:36:34 si last message repeated 1 time Feb 3 10:36:34 si nfs: [ID 563706 kern.notice] NFS server nati ok Feb 3 10:36:34 si last message repeated 1 time Feb 3 10:46:13 si nfs: [ID 456612 kern.notice] file temporarily unavailable on the server, retrying...

Feb 3 14:02:13 si nfs: [ID 333984 kern.notice] NFS server nati not responding still trying in addition i have a samba installed on the NFS server that export the same folders in diffrent share names for a windows users. can it be some file locks or conflicts between the samba and NFS though i cant see any samba errors also. will thank any clue or a lead. Thanks in advanced
