You're running out of space in the JVM's Metaspace region (where class metadata is stored), not system memory. Metaspace is roughly equivalent to PermGen from Java 7 and prior versions. The exception means that you have more classes being loaded in the JVM than will fit in your currently defined Metaspace. My first suggestion would be to try increasing the size of Metaspace via the JVM argument MaxMetaSpaceSize. I'd also suggest reading up on the exception in the Oracle documentation for Java 8, here https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/memleaks002.html (search for Metaspace). > # > # There is insufficient memory for the Java Runtime Environment to continue. > # Native memory allocation (malloc) failed to allocate 1380048 bytes for > Chunk::new > # An error report file with more information is saved as: > # /tmp/hs_err_pid11058.log > > Regards, > Rakesh Kumar Kanduri > Disney ABC Television Group > Cognizant Technology Solutions Ltd. | > www.cognizant.com<http://www.cognizant.com/> > US Dial: +1 973 368 9600 Ext 670002 > Offshore Direct: +91-40-66690-002 | Cell: +91 9985429546 > DATG IT ESB On Call # +1 818 869 2690 > Email - > datg.dl-esb.infrastruct...@disney.com<mailto:datg.dl-esb.infrastruct...@disney.com> > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
