vmbk.pl stops after a few VM when executing from cron (no scsi disk found)

Hello.

i'am doing vmbk.pl snapshot backup over nfs trough nfs mapped disk (/vmfs/volumes/nfs02/)the scripts run fine when running manual but when executing in the cron the scripts ends with the message no scsi disk found , see the log attached.

on stderror i can see the following error just before the error occurs.

Check space on destination directory:

/vmfs/volumes/NFS02/

125000 MByte Free

Use of uninitialized value in numeric lt (<) at /usr/local/bin/vmbk.pl line 3693.

-

iam not very familiar with perl but it seems the code try to use an unititialized value.

why is the value not initialized when ran from cron?

im running vmbk.pl 3.0 rev11 on esx 3.02

Thanks
