Doesn't look like a performance problem - moving to Java in General (intermediate)...

Hi

the realloc funtion changes the size of an allocated memory block: so it may be that your thread/application is bumping its head against the ceiling of heap memory allocated to the JVM by the OS.

You could always try specifying the maximum JVM heap size with the -Xmx flag and see what happens.

Hope that helps
