Environment : Netbackup 4.5 MP2 on Windows NT/2000

We get the following error with a full backup :

29/12/2002  13:02:25    dvvbewkgbu00      dvvbe000fs02      Critical    0
General     *NULL*
29/12/2002  13:02:25    dvvbewkgbu00      dvvbe000fs02      Error 5104
Backup      db_FLISTsend failed: system call failed (11)

I checked the troubleshooting guide and there it says that it should be
related to a filesystem being full (on the master server I presume). That
is not the case. The Netbackup master server software is installed on the D
drive and there are several Gb free space available. The C drive has 253Mb
free space.

Can anyone explain me what happens when bpbkar on the client sends it's
file information through bpbrm and bpdbm on the master server ? Is this
file list data directly written in the file database or is there somewhere
a temporary file kept on the master server ? I could not find anything
about that on the Veritas support site or on the Internet.

Thanks,
Bruno
