Seeing following commit errors.

Looking at the code,
public final void prepareCommit() throws IOException {
ensureOpen();
prepareCommitInternal();
}
private void prepareCommitInternal() throws IOException {
synchronized(commitLock) {
ensureOpen(false);
if (infoStream.isEnabled("IW")) {
infoStream.message("IW", "prepareCommit: flush");
infoStream.message("IW", " index before flush " + segString());
}
if (hitOOM) {
throw new IllegalStateException("this writer hit an
OutOfMemoryError; cannot commit");
}
It simply checking a flag if it hit OOM? What is making to check and set
the flag? What could be the conditions? Thanks.
