Hi there,
Here is my config
Server version: Apache Tomcat/8.0.14
Server built: Sep 24 2014 09:01:51
Server number: 8.0.14.0
OS Name: Linux
OS Version: 3.13.0-36-generic
Architecture: amd64
JVM Version: 1.7.0_65-b32
JVM Vendor: Oracle Corporation
The virtual (qemu) server runs with 4GB RAM
I have two tomcat instances running on the same server with setenv.sh
set to:
-Xmx800m -XX:MaxPermSize=192m
Here is my problem:
I have two configured instances on this server
After some time playing with stopping and starting with those instances
began to take AGES to startup (~10min)
03-Oct-2014 09:11:05.973 INFO [localhost-startStop-1]

ureRandom instance for session ID generation using [SHA1PRNG] took

Workaround:
I tried to add -Djava.security.egd=file:/dev/./urandom with success (in
setenv.sh).
But why would I *suddendly* have to use this additional param ? Never
got this problem in tomcat before...
Could it be linked to the VM ?
Thanks
