v7.1.1 lost /ip/ipsec/identity configuration

I am running v7.1.1 on RB4011 and found all configurations in /ip/ipsec/identity are lost randomly.
Is this a known issue of v7 ?

Unable to reliably reproduce it, but it happens twice in a week after upgrade to v7.

  • Update:
    /system/reboot under load (30% CPU) seems able to reproduce (3/3 all lost configurations), while idle reboots have no issue.

Glad to see this as I thought I was going mad. Seeing exactly the same thing on 7.1.5 on an RB1100Dx4

All the other IPSEC config remains but the identities all disappear on some reboots.
