------------------------------------------
Summary: System vm startup scripts calculate jvm memory wrong
Key: CLOUDSTACK-5205
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5205
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: SystemVM
Affects Versions: 4.2.0
Reporter: John E Vincent
While attempting to provision beefier system vms, we discovered this bug.
The `_run.sh` script in the system vm calculates jvm memory based on 80% of the
total memory on the system. This is great up until the point 80% of memory goes
above ~1.9G. The system vm templates are all 32-bit and so calculating the size
too high will cause the agent jvm to fail to start.
The fix is pretty simple with a final sanity check:
if [ $maxmem -gt 1900 ]
then
maxmem=1900
fi
