| Subject: lockd: Try to reconnect if statd has moved |
| |
| From: Benjamin Coddington <bcodding@redhat.com> |
| |
| commit 173b3afceebe76fa2205b2c8808682d5b541fe3c upstream. |
| |
| If rpc.statd is restarted, upcalls to monitor hosts can fail with |
| ECONNREFUSED. In that case force a lookup of statd's new port and retry the |
| upcall. |
