[Bug 462140] Re: maximum 61 "running" instances, others shutting down

Wed Oct 28 12:31:49 GMT 2009

new tests : v27.1 rebooted cluster, creating security groups, 
VNET_ADDRSPERNET="512"
VNET_PUBLICIPS="192.168.3.1-192.168.5.254"

launching vms :

export EMI=emi-4158125D
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group2
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group3
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group4
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group5
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group6
euca-run-instances $EMI -n 50 -k mykey -t c1.medium --addressing private --group group7
euca-run-instances $EMI -n 20 -k mykey -t c1.medium --addressing private --group group8

the vms are launching fine, but only 32 end up running, the others are terminated.
when i had the "ADDRSPERNET" problem the vm was not able to launch.

for the same cluster setup, yesterday it was 64 vms, now it's 32 ...

result : some entire groups are being terminated ??? (groups 2,5,6,7 ...)

now if i try to relaunch the group2 (50 vms), they are accepted,
"pending" and terminated ...

note that it's not a first instanciated first terminated queue : i have
vms from group 3 and 4 and not from groups 5 6 7.

strange.
