from syslog: "Use of uninitialized value in concatenation"

[bread-baker]

this is probably a not too important issue, but the following is caused an emergency log rotation for /var/log/syslog :

Oct  4 06:33:04 fbc158 pvestatd[396670]: WARNING: Use of uninitialized value in addition (+) at /usr/sh
are/perl5/PVE/OpenVZ.pm line 81.
Oct  4 06:33:04 fbc158 pvestatd[396670]: WARNING: Use of uninitialized value in addition (+) at /usr/sh
are/perl5/PVE/OpenVZ.pm line 81.
...
# and a diff line number:
Oct  4 06:33:04 fbc158 pvestatd[396670]: WARNING: Use of uninitialized value in concatenation (.) or string at /usr/bin/pvestatd line 208.

Oct  4 06:33:04 fbc158 pvestatd[396670]: WARNING: Use of uninitialized value in concatenation (.) or string at /usr/bin/pvestatd line 208.

as I said it is probably a small issue that is already known to devs, however it clutters and filles up /var/log/syslog .

IIRC, this was also printed out when doing a pveca -l.  The memory usage showed a raw number in scientific notation instead of a percentage being used.  But I was in a hurry and working on something else at the same time, so I didn't document it.  My bad.

Hi
I got lots of these:

point here seems to be: if you migrate an openvz-container to the new proxmox it expects a lot of things to be there (obviously in the config file) which there are not. after manually confirming memory-settings for each container everything is quiet again in the syslog.

Just uploaded a fix to avoid those warning (pve-manager 2.0-35)
