Exception in session.releaseRef jinterop

In some situations when executing session.releaseRefs line 347 of class JISession is raising exception like 0x8001FFFF broken pipe, or 0x80010108 Received fault. (unknown). In catch clause is just logging the error, in this case is going to happen a memory leak? there is another solution to deal with this kind of exception beside logging the error?
