Hi, Ruben,
I confirm I get the same timing when I do NOT use the SSL proxy:

I have something else which is strange: there are 2 VMs in my list which
do not have a "state" defined. I cannot delete them either:
$ onevm list | grep -v runn
ID USER GROUP NAME STAT CPU MEM
HOSTNAME TIME
22976 lsfadmin batch LXBATCH 0 0K lxbst0541.cern.
02 14:12:07
23467 lsfadmin batch LXBATCH 0 0K lxbst0511.cern.
00 04:33:07
$ onevm delete 22976
$ onevm delete 23467
$ onevm list | grep -v runn
ID USER GROUP NAME STAT CPU MEM
HOSTNAME TIME
22976 lsfadmin batch LXBATCH 0 0K lxbst0541.cern.
02 14:12:23
23467 lsfadmin batch LXBATCH 0 0K lxbst0511.cern.
00 04:33:23
Now I wonder if that might be related... I suppose I will need to
micky-mouse in my mysql ddb to get rid of those?
Thanks a lot for your support!
Cheers,
Ulrich
