32bit RHEL 5.9 client backup to 64bit NetBackup Server v7.x...

Hi,

I have an N5220 master/media appliance running v2.5.2 (with NetBackup v7.5.0.5) and it can backup a 32bit RHEL 5.9 with NetBackup Client v6.5 (no patch) just fine.

However, when I bptestbpcd from a 64bit RHEL 6.4 master/media running NetBackup Server v7.6.0.1 - I get:

...
16:30:18.400 [23213] <2> put_string: cannot write data to network:  Connection reset by peer (104)
16:30:18.400 [23213] <2> bpcr_put_vnetd_forward_socket: put_string /tmp/vnet-blah-blah failed: 104
16:30:18.400 [23213] <2> local_bpcr_connect: bpcr_put_vnetd_forward_socket failed: 24

16:30:18.400 [23213] <16> bptestbpcd main: Function ConnectToBPCD(xxxxx) failed: 24
<16>bptestbpcd main: socket write failed
...

Is anyone out there successfully backing-up a 32bit RHEL 5.9 NetBackup Client v6.5.x (patched) client to NetBackup v7.6.x.x ?

If so, which v6.5.x patch version works for you?

Many thanks.
