NETCONF error: Locked session


Your session is locked, and you see an error message like this:

<?xml version="1.0" encoding="UTF-8"?>
<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="101">
    <error-message>Access to the requested lock is denied because the lock is currently held by another entity</error-message>
    <session-id>session is locked by 12969</session-id>


There is a lock on your NETCONF session — this may be due to another user, or you may have issued a lock in another NETCONF session. You can't make changes in this session while the <lock> RPC is active.


If the <lock> RPC was already active at the start of your session then other operations should still work. Use the <unlock> or <closesession> operation to clear the lock.
If another session holds the lock, try to determine who controls that session. Then:
  • If you are able to determine who holds the lock, co-ordinate with them to complete your operations.
  • If you are unable to determine who holds the lock, then you may simply have to wait and try again later. For information about the duration, see RFC6241, 7.5 <lock>.
