Subject Re: CloudStack 4.5.2 with tomcat6 out of memory
Date Thu, 15 Oct 2015 10:08:33 GMT
Hi,

Just FYI, not sure if it is related: 
I also noticed that it reports “OutOfMemory” even when there is another issue, like exhausted
file descriptors or too many processes. Try bumping those limits as well.

Regards,
Remi
