Linux: Out of Memory:kill process 1270 (Java) score 478 or sacrifice child or: Java.lang.OutOfMemoryError:PermGen space

Solution: Insufficient memory, automatically kill the process, that is, killed the project process, the project can not start

The reason for this problem is that low memory is exhausted. "Kernel uses low memory to track all memory allocations, and once the low memory is exhausted, the process will be avira to keep the system running properly." The OOM Killer is a layer of protection that avoids the problem of not being too serious when Linux is in storage, and kills the unimportant process.

Solution: Found: bin/catalina.sh, in front of this echo "Using catalina_base: $CATALINA _base" plus this one, java_opts= "$JAVA _opts-server-xx: Permsize=128m-xx:maxpermsize=512m "
