Error occurred during initialization of VM
Could not reserve enough space for object heap
---------------------------------------------------

Solution  :
-----------
Cause :
---------

System was unable to reserve 1600M java heap memory for the jvm …

Solution : 

Reduced the java heap memory to be used by the jvm to 512M (updated the s_jvm_options  in the CONTEXT_FILE and ran autoconfig)


Before:
<jvm_options oa_var="s_jvm_options" osd="Linux">-verbose:gc –Xmx1600M –Xms1600M -XX:MaxPermSize=128M -XX:NewRatio=2 -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:
+PrintClassHistogram -XX:+UseTLAB -XX:+CMSClassUnloadingEnabled</jvm_options>

After:

<jvm_options oa_var="s_jvm_options" osd="Linux">-verbose:gc -Xmx512M -Xms512M -XX:MaxPermSize=128M -XX:NewRatio=2 -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -
XX:+PrintClassHistogram -XX:+UseTLAB -XX:+CMSClassUnloadingEnabled</jvm_options>

After this Run Autoconfig and retest the issue.
