Your application has used all the memory it has allocated, prevent the error by allocating more memory, unless your application has a memory leak - in which case, find the leak and fix it. You're on a linux variant presumably? Please state your exact JVM version, & OS info. In this case the amount of hardware RAM available would be useful too. Do you have any memory settings in your JAVA_OPTS or CATALINA_OPTS? (If you're not sure, they look like "-Xmx1024M" for example.) Execute the following command to find out what the heap is using: jmap -heap <pid> p
