I have a tomcat as my web-server, it stopped down automatically with the given Error -
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007
Java was not able to allocate enough memory, i.e. it's not Java's heap limit that's in the way but rather no more memory available to be given to Java by OS. Check that the machine is not running out of memory. And first clean ram or increase ram then check if again there is an out of memory error then increase heap size:
-Xms128m
min(heap size)
-Xmx512m
max(heap size)
-XX:MaxPermSize
max(perm size)
