Description

OOME in IPC server handler causes the IPC handler to abort, but the client never learns about this, so it waits and waits and waits... I have seen Heritrix writer threads that have been waiting for 7+ hours. And, the OOME does not take down the HRS, so it stays up in some degraded state. E.g.:
